Answer: p*$4 + d*$3 ≥ $24
Explanation:
The price P of popcorn is P = $4, the pricec of a drink is D = $3
He only has $24
The equation that represents the number of popcorns and drinks he can buy us:
p*$4 + d*$3 ≥ $24
This means that the maximum amount of money he can spend is $24.
In this equation you can give the value of p or d, and then find the maximum possible value for the other variable.
