Question

Kevin and his children went into the movie theater and he bought $54.75 worth of drinks and pretzels. Each drink cost $5.50 and each pretzel costs $3.25. He bought 2 more drinks than pretzels. Determine the number of drinks and the number of pretzels that Kevin bought.​

Answer 1

7 DRINKS AND 5 PRETZELS

Explanation:

let he bought x pretzels and hence x+2 drinks

cost of x pretzels x×3.25 =3.25x

cost of x+2 drinks (x+2)×5.50 =5.50X+11

NOW SET THE EQUATION

3.25X+5.50X+11 =54.75

8.75X = 54.75-11

8.75X =43.75

X = 43.75/8.75

X= 5 THIS IS NUMBER OF PRETZELS

X+2= 7 THIS IS NUMBER OF DRINKS
