Question

Write a system that describe the situation:

Alex purchased 2 hotdogs for x dollars each and 4 popcorn balls for y dollars each for a total cost of $14.00. Marion purchased 4 hotdogs for x dollars each and 7 popcorn balls for y dollars each for a total $26.00.

Answer 1

2x + 4y = 14
4x + 7y = 26

Answer 2

Do u need to solve the equation for x & y

Answer 3

i think so

Answer 4

2x + 4y = 14 -2(2x + 4y = 14) -4x+-8y=-28
4x + 7y = 26 4x + 7y = 26
-y=-2
y=2

2x + 4(2)=14
2x - 8 = 14
2x = 6
x = 3
Hot dogs cost $3 and popcorn balls cost $2 (3,2)

Answer 5

nicely done DSS :)
