Question

Bella and her children went into a movie theater and she bought $48 worth of drinks and candies. Each drink costs $5 and each candy costs $4.50. She bought a total of 10 drinks and candies altogether. Determine the number of drinks and the number of candies that Bella bought.

Answer 1

Drinks=6

Candies=4

Explanation:

Let the number of drinks be x while candies be y. Considering the numbers

X+y=10

Making x the subject of the formula then x=10-y

Considering the cost then

5x+4.5y=48

Substituting x here then

5(10-y)+4.5y=48

50-5y+4.5y=48

0.5y=2

Y=4

X=10-y

X=10-4=6
