Sagot :
Answer:
[tex]40 = \frac{24}{.5d+.75t}[/tex]
Step-by-step 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
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
