Question

Noah has $56x. He bought y soccer balls. Each soccer ball costs $24. Write and factor an algebraic expression for the amount of money Noah has now.

Sarah's age is one-fourth of Kim's age now. In 8 years, Kim will be n years old. Write an expression to represent Kim's age now.

In 8 years, Kim will be n years old. Write and simplify an expression to represent Sarah's age now.

In 8 years, Kim will be n years old. Write and simplify an expression to represent Sarah's age ten years from now.

In 8 years, Kim will be n years old. If Kim will be 44 years old in ten years, how old will Sarah be in ten years?

sorry if its too much

Answer 1

#1.

starts with 56x
spends 24y
amount left = 56x - 24y = 8(7x - 3y)

#2:
If 8 years from now, Kim will be n
her present age is n-8

Sarah's age has nothing to do with it, is there some kind of typo?

#3, ahh, are the all part of the same question?

so if Kim is now n-8 and Sarah is (1/4) of her age,
Sarah is now (1/4)(n-8) = 1/4 n - 2

try the others following similar logic
