Shana and Marie will update parts of their computer system. They will update the motherboard for $259.99, 2 USB
ports for $39.95 each, and the DVD drive for $79.49. Shana will save $12.50 per week and Marie will save $15.50
per week. Which inequality can be used to find w, the number of weeks it will take Shana and Marie to save enough
money for the parts?

Respuesta :

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

Shana:

12.50 * w = 419.38

12.5w = 419.38

w = 419.38/12.5

w = 33.5504

Marie

15.50*w = 419.38

15.5w = 419.38

w = 419.38/15.5

w =27.0568
