Question

Faith is saving up to buy a new bicycle. She already has $40 and can save an additional $6 per week using money from her after school job. How much total money would Faith have after 8 weeks of saving? Also, write an expression that represents the amount of money Faith would have saved in w weeks.

Answer 1

Expression:

`s(x)=40 + 6x`

where s(x) is the savings and x is the number of weeks.

Faith will save $88 in 8 weeks.

Explanation:

We are given the following in the question:

Money Faith already have = $40

Additional earning per week = $6

Thus, we can write the following expression for the saving in x weeks.

`s(x)=40 + 6x`

where s(x) is the savings and x is the number of weeks.

We have to find total money saved by Faith in 8 weeks.

We put x = 8 in the above equation.

`s(8) = 40+6(8) = 88`

Thus, Faith will save $88 in 8 weeks.
