Hugo:

12-9=3years
62-56=6inces
6 is what present of 56?
6 = x * 56
6/56=x
3/28=x
x=0.10714286
the the nearest tenth,
x=0.1

Interest:
x=opening deposit
y=interest rate (some decimal number or percent[which is then turned into a decimal])
$3262.50 over the course of 9 months is
3262.50/9=$362.5 per month
What is the interest rate of the equation?
x*y=362.5
x=362.5/y

Total Cost, Boat:
sales tax equations:
x=price
y=percent tax
z=final price
x+(x*y)=z
x*(1+y)=z
$1600, 5.5%
1600*.055=88
so sales tax is $88, plus(!) the cost of the actual boat so
1600+88=1688
total cost=$1688

CD Player1-Discount
Sales: % less/markdown
x=original price
y=percent discount
z=final price
x-(x*y)=z
x*(1-y)=z
x=$89, y=solve for, z=$80
x*(1-y)=z
(x*(1-y))/x=z/x
1-y=z/x
-1 = -1
-y=(z/x)-1
y=1-(z/x)
y=1-(80/89)
y=1-.8989
y=0.1011
10.11% discount

I gave you the equations, and the explanations, so hopefully, you will be able to get farther the next time. the answers you gave were correct, but you were missing the next step to the problems. If you need/want to, write the equations down, so that you have them if you ever need them. and if you learn how to "translate" English math problems to math equations (like I did in Hugo), word problems won't as difficult. It takes a while, and a lot of practice, and it helps if they are lined up the correct way (like how I wrote Hugo) and not backward (like they sometimes are) but practice and you'll get it.

A customer earned $3,262.50 interest on a 9-month CD. How much was the opening deposit

Find the percent of discount to the nearest percent.


CD player: regular price, $89
sale price, $80

To find the percent of increase in Hugo's height, we can use the formula:

Percent increase = (New height - Old height) / Old height * 100

Given that Hugo's old height was 56 inches and his new height is 62 inches, we can substitute these values into the formula:

Percent increase = (62 - 56) / 56 * 100
Percent increase = 6 / 56 * 100
Percent increase = 0.107 * 100
Percent increase = 10.7%

Therefore, the percent increase in Hugo's height is approximately 10.7%.

Now, let's move on to the next question.

To determine the opening deposit for the 9-month CD, we need to know the interest rate. Since the question only provides the amount of interest earned (3262.50), we cannot determine the opening deposit without additional information. The opening deposit is dependent on the interest rate and the duration of the CD.

Next, let's move on to the question regarding the total cost of a boat.

The total cost of the boat, including 5.5% sales tax, can be calculated by adding the sales tax to the boat's price.

Sales tax = 5.5% of the boat's price
Sales tax = (5.5 / 100) * 1600

Total cost = Boat's price + Sales tax
Total cost = 1600 + (5.5 / 100) * 1600
Total cost = 1600 + 88
Total cost = 1688

Therefore, the total cost of the boat, including 5.5% sales tax, is $1688.

Now, let's move on to the question about the CD player.

The total cost of the CD player, including the discount and sales tax, can be calculated by subtracting the discount from the regular price and then adding the sales tax.

Discount = Regular price - Sale price
Discount = 89 - 80

Sales tax = 5% of the CD player's price
Sales tax = (5 / 100) * 80

Total cost = Sale price + Sales tax
Total cost = 80 + (5 / 100) * 80
Total cost = 80 + 4
Total cost = 84

Therefore, the total cost of the CD player, including the 5% sales tax, is $84.

Next, let's address the question about the total cost of a computer.

The total cost of the computer, including the 7% sales tax, can be calculated by adding the sales tax to the computer's price.

Sales tax = 7% of the computer's price
Sales tax = (7 / 100) * 1500

Total cost = Computer's price + Sales tax
Total cost = 1500 + (7 / 100) * 1500
Total cost = 1500 + 105
Total cost = 1605

Therefore, the total cost of the computer, including the 7% sales tax, is $1605.

Moving on to the next question about the total price of the CD player.

The total price of the CD player, including the 5% tax, can be calculated by adding the tax to the CD player's price.

Tax = 5% of the CD player's price
Tax = (5 / 100) * 99

Total price = CD player's price + Tax
Total price = 99 + (5 / 100) * 99
Total price = 99 + 4.95
Total price = 103.95

Therefore, the total price of the CD player, including the 5% tax, is $103.95.

Lastly, let's address the question about the percent discount.

The percent discount can be calculated using the formula:

Percent discount = (Regular price - Sale price) / Regular price * 100

Given that the regular price of the calendar is $9.00 and the sale price is $2.25, we can substitute these values into the formula:

Percent discount = ($9.00 - $2.25) / $9.00 * 100
Percent discount = $6.75 / $9.00 * 100
Percent discount = 0.75 * 100
Percent discount = 75%

Therefore, the percent discount on the calendar is 75%.
