Question

You would like to order tulips for your garden. Through a catalog, you can purchase them for $0.75 each, plus a $3.00 shipping fee. If your budget is $15, how many bulbs can you order?

Answer 1

Let's call x to the number of tulips you can buy

Each tulip costs $0.75, then x tulips cost 0.75x

There is also a $3.00 shipping fee. Then, the total cost of x tulips is 0.75x + 3.

Your budget is $15, then:

0.75x + 3 = 15

Solving for x:

0.75x = 15 - 3

0.75x = 12

x = 12/0.75

x = 16
