Answer:
12.5w = 419.38
and
15.5w = 419.38
Step-by-step explanation:
find the total cost of all the computer parts.
= 259.99 + 2* 39.95 + 79.49 = $419.38
Shana will save $12.50 per week and Marie will save $15.50
per week
therefore we can create two inequalities
12.50 * w = 419.38
12.5w = 419.38
w = 419.38/12.5
w = 33.5504
15.50*w = 419.38
15.5w = 419.38
w = 419.38/15.5
w =27.0568
