Question

Purchasing the correctly sized BMX bike is based on the height of the rider. In order to fit a customer, the salesman can use the equation b=0.29h+1.35 where b is the size of the BMX bike frame in inches and h is the height of the rider in inches.
1. As a rider increases one inch in height, the bike frame increases 0.29 inches.
2. The height of the rider gets multiplied by 0.29.
3. The bike frame increases 0.29 inches for every 1.35 inches of the rider's height.
4. As a rider's height increases 1.35 inches, the bike frame increases one inch.

Answer 1

Answer: Your best answer is A.

Explanation: 1.35 is a constant and thus is does not change. The equation can be simplified to-
“b = (0.29 x h)+ 1.35”
So, if your rider is say 60 inches tall, the equation would change to-
“b = (0.29 x 60)+ 1.35”
Then to-
“b = (17.4) + 1.35” or “b = 17.4 + 1.35”
And therefore the size of the BMX bike frame in inches would be-
“b = 18.75”

Hope this helped :)
