Question

Alex goes to a movie on Saturday for $10. While there, he pays $3 for each item he buys at the concession stand.

Which equation best represents this information?
y = 10x + 3
y = 3x - 10
y = 3x + 10
y = 10x - 3

Answer 1

y = 3x + 10

Explanation:

y represents total he pays

x represents items he buys

total he pays = $3 for each item + $10 movie

y = 3x + 10

Answer 2

y = 3x-10
he has 10 dollars and each item is $3
