So...
If he is only able to purchase $450.00 worth of gift cards, and a total of 15,
begin by.
Doing simple math.
Take
$50.00 * 5 (You know he can purchase one 50 card for sure because of the $50. in $450
$50.00 * 5 = $250.00
Next take 15-5 = 10 (Amount of gift cards left to purchase)
Finally Take $20 * 10 = $200
When you add your restaurant give card and movie gift card amount you will receive the answer of $450.00 (to double check your answer)
When you add 5 + 10 you will receive the answer of 15 (to check the amount he has to purchase)
The correct answer would be
Mr. Thomas can purchase a total of 5 restaurant gift cards and 10 movie gift cards to give to his employees.
