Question

Jason is decorating his house and decides to paint one of the bedrooms blue. One tin of 500mL blue paint costs $11.50. To finish the whole bedroom, he needs 4L of blue paint. How much will it cost Jason to paint this bedroom?

Answer 1

1.You have that:

- One tin of 500 mL blue paint costs $11.50.
-Jason needs 4 L of blue paint.

2. First, you must convert 4 L to mL, as below:

1 L----1000 mL
4 L----x

x=4x1000/1
x=4000 mL

3. If 500 mL costs $11.50, how much will it cost 4000 mL?

500 mL-----$11.50
4000 mL---x

x=(4000 mL)($11.50)/500 mL
x=$92.00

How much will it cost Jason to paint this bedroom?

The answer is: $92.00
