X- when hugo was 9 years old he was 56 inches
tall. hugo is now 12 years old and he is
62 inches tall. fins the percent of increase in
hugos height to the nearest tenth
X- a customer earned 3262.50 interest on a
9-month cd. how much was the opening
**total cost-- 1600 boat, 5.5% sales tax
X- cd player-- regular price, $89, sale price $80
**what is the total cost of a computer that had a
price of $1500 and sales tax of 7%
**a cd player costs $99 plus 5% tax.
what is the total price of the cd player
**find the percent of discount to the nearest
percent if a calendars regular price is $9.00
and the sale price is $2.25
** 1600 • 0.055 = 88
**1500 • 0.07 = 105
**99 • 0.05 = 4.95
**2.25/9 = 25%
X = I don't know please help.
6 is what present of 56?
6 = x * 56
the the nearest tenth,
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?
Total Cost, Boat:
sales tax equations:
so sales tax is $88, plus(!) the cost of the actual boat so
Sales: % less/markdown
x=$89, y=solve for, z=$80
-1 = -1
discount is 75%
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.
