Question

Joe wants to purchase a new skateboard. He already has $40 and can save $20 each week from his job. Write a linear equation to represent the total amount he has after ‘w’ weeks.

A) T = 20 + 40w

B) T = 60w

C) T = 40 + 20 + w

D) T = 40 + 20w

Answer 1

Option D: 40+20w is the correct answer

Step-by-step explanation:

We have to convert the given statement in the problem to find the correct choice

Let w be the number of weeks

As Joe already has $40, it will be constant that will not change

And the money he saves in w weeks by saving 20 dollars per week will be:

20w

Combining the both terms we get the total cost as:

$T = 40+20w$

Hence,

Option D: 40+20w is the correct answer
