Set it up as a direct variation: y/x=k, where k is the constant of variation. (20/3)/30=k gives us a k value of 8/9. The function would be y=8/9x
To determine the total class the whole class spent, you just have to simply add the individual costs of the three books. Using parenthesis, the solution can be written in the following two ways:
($15 + $9) + $12 = $36
$15 + ($9 + $12) = $36
No matter where you put the parenthesis, the final answer doesn't change. This is because of the Commutative Property of Addition. The order does not matter.
1 kilometer = 0.6214 miles
120 to 130 kilometers per hour = 120 x 0.6214 to 130 x 0.6214 = 74.56 to 80.78 miles per hour.
