Will someone please write an expression for these? I am horrible at this, i will solve them though.
1.) Logan withdrew $32 from her bank account. After her withdrawal, her balance was $8. How much was originally in her account?
2.)The baseball birthday batter package at a minor league ballpark costs $192. The package includes tickets, drink, and cake for a group of 16 children. What is the cost per child?
3.)After taxes,Alexandras take-home pay is 7/10 of her salary before taxes. If her take-home pay was $392, what was her salary before taxes?
4.)Your weight on the moon is about 1/6
of your weight on Earth. If a person weighs 16 pounds on the moon, what is his weight on earth?
5.)Paul bought a student discount card for the bus. The card cost $7, and it allows him to buy daily bus passes for only $1.50. in his first month, Paul spent a total of $29.50 to ride the bus. How many daily bus passes did he buy?
6.)Jennifer is saving money to buy a bike. The bike costs $245. She has $125 saved, and each week she adds $15 to her savings. How many weeks will it take Jennifer to save enough money to buy the bike?
What do you mean "write an expression?"
1. $38 + $8 = $46
Sra
Like, so i can solve it.
I will do a few.
1) Balance-32=8
6) 245=15*weeks+125
4. WeightonEarth*1/6=16
thank you! how would you solve 1/6e = 16?
multply each side by six.
thank you so much, i am having hard times with number 3 though.Can you please hint me some info on how to write it?
3.
0.7x = 392
Bryce -- these don't look like h.s. senior problems.
Its for Jacob, i use jiskha as a resource for stuff i don't know. I tutor only Biology and English, very little math.
1.) To find out how much was originally in Logan's account, you can set up an equation. Let's say the amount originally in her account is "x".
The equation would be: x - $32 = $8
To solve for "x", you can add $32 to both sides of the equation:
x - $32 + $32 = $8 + $32
This simplifies to:
x = $40
So, originally, there was $40 in Logan's account.
2.) To calculate the cost per child, you can divide the total cost ($192) by the number of children (16).
$192 / 16 = $12
Therefore, the cost per child is $12.
3.) To find out the salary before taxes, we can set up an equation using the information given. Let's say the salary before taxes is "x".
The equation would be: (7/10) * x = $392
To solve for "x", you can divide both sides of the equation by (7/10):
(7/10) * x / (7/10) = $392 / (7/10)
This simplifies to:
x = $560
So, the salary before taxes was $560.
4.) To find the weight on Earth, you can multiply the weight on the moon by 6. Let's say the weight on Earth is "x".
The equation would be: (1/6) * x = 16 pounds
To solve for "x", you can multiply both sides of the equation by 6:
(1/6) * x * 6 = 16 pounds * 6
This simplifies to:
x = 96 pounds
So, the person's weight on Earth is 96 pounds.
5.) To find out how many daily bus passes Paul bought, you can subtract the cost of the student discount card from the total amount spent on bus passes and divide it by the cost of each daily bus pass.
Let's say the number of daily bus passes Paul bought is "x".
The equation would be: ($29.50 - $7) / $1.50 = x
This simplifies to:
$22.50 / $1.50 = x
x = 15
So, Paul bought 15 daily bus passes.
6.) To find out the number of weeks it will take Jennifer to save enough money, you can subtract the amount she has already saved from the cost of the bike and divide the result by the amount she saves per week.
Let's say the number of weeks Jennifer will take to save enough money is "x".
The equation would be: ($245 - $125) / $15 = x
This simplifies to:
$120 / $15 = x
x = 8
So, it will take Jennifer 8 weeks to save enough money to buy the bike.
