Garrett and Carter went to the movies last weekend. Together they bought 2 drinks and 2 popcorns. They spent a total of $12.50.
Thursday they met several other friends at the same theater. They purchased 6 drinks and 5 popcorns for a total of $33.75. What was the cost of one drink and one popcorn?
1 answer:
Since Garrett and Carter bought popcorn and drinks, we have to figure out how much money is 1 drink and 1 popcorn. I figured the best way is to figure out half of $12.50 because 2 drinks and 2 popcorn cost that amount of money. You divide $12.50 by 2 to figure out half of that amount. The quotient equals to $6.25.

Step-by-step explanation:
The corresponding sides of similar Δs are proportional.
ΔADE ~ ΔABC ⇒ =
=
AD = x + 8 ; DE = 8
AB = x ; BC = 6
=
⇔ 8x = 6(x + 8) ⇒ <em>x = 24</em>
