Question

Carolina bought a t-shirt for $20 and two admission tickets to a concert. Let x represent the cost of an admission ticket. The expression 2x + 20 represents the total amount Carolina spent. What was the total amount that Carolina spent if each admission ticket, x, was $40?

Answer 1

$100

Explanation:

40 is x. So, just plug in 40 into the equation:

2(40)+20=?

80+20=?
