Question

Pablo purchased adult and youth tickets for the football game. He bought x adult tickets for $74 each and y youth tickets for $35. Write an expression that can be used to show the total cost, C, of all tickets. (4 points) a C = (74 + 35)x b C = (74 + 35)(x + y) c C = 74y + 35x d C = 74x + 35y

Answer 1

The answer is C= 74x +35y

You should have the appropriate variable with the appropriate price, so the x for adult tickets goes with the prices for adult tickets and y for number of youth tickets to go with youth prices.

Since these numbers are separate and different, you don't want to combine them like A and B do.

Answer 2

c=74x+35y (answer c)

Explanation:

The adult tickets are x and the youth tickets are y. They are not influenced by but add up to the total coast.

A does not work because it is 35+74 multiplied by the amount of tickets needed for adults. B does not work because it mulitplies the cost of tickets by the amount of tickets needed. Therefore C is right.
