Question

Marcus raised $24 by selling 40 packs of chips for the football club She sold Doritos for 50 cent each and takis for 75 cents each Write a system of equation that could be used to determine how many of each type of chips

Answer 1

24=.5d+.75t and since we are told d+t=40 so we could rewrite to solve for either t or d

24=.5(40-t)+.75t, 24=20-.5t+.75t, .25t=4, t=16

24=.5d+.75(40-d), 24=.5d+30-.75d, -6=-.25d, d=24

Answer 2

`40 = (24)/(.5d+.75t)`

Explanation:

d= number of Doritos sold

t= number of Takis sold

The 40 is the number of packs Marcus sold. The $24 as the numerator represents the total amount of money raised by selling the chips. It is divided by .5d + .75t (this represents the 50¢ • the number of Dorito bags sold plus the 75¢ • the number of Takis bags sold).

The d and t are unknown because that is what you are trying to figure out.

Hopefully this makes sense and is right
