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

D

Step-by-step explanation:

Joe already has $40 and can save $20 each week. the total amount he can save in a given number of weeks is $20 multiplied by the that number of weeks which in this case is w so 20w. To find the total T of the amount he has after w weeks, you add the amount he already has to the amount saved. So the equation would be T=40+20w
