6hrs = 360 minutes
360/7.5 = 48 bottles required
500g = 0.5kg
48x0.5 = 24 kg
24x 5 = 120p
The x represents the ticket prices and the y represents the popcorn price. If we distribute the expression, we get 4x +2x + 2y. This shows us that all 6 people bought a ticket, and two bought popcorn. Now plug in the given values and solve.
6*7.25 + 2*3.25 = $50
A purchase is one where you purchase it and sales is one you sell :)
Hope that helped!
Answer:
The answer would be d(c(x)) = .60x - 5
Step-by-step explanation:
In order to write an equation for d(c(x)), start with the d(y) equation.
d(y) = .80y - 5
Now input the c(x) equation in for y and then solve.
d(c(x)) = .80(.75x) - 5
d(c(x)) = .60x - 5
