Answer:
<em>12.5w = 419.38</em>
<em>and</em>
<em>15.5w = 419.38</em>
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
<h2><u> Shana:</u></h2>
12.50 * w = 419.38
<em>12.5w = 419.38</em>
w = 419.38/12.5
w = 33.5504
<h2><u>Marie</u></h2>
15.50*w = 419.38
<em>15.5w = 419.38</em>
w = 419.38/15.5
w =27.0568
