Question

diane works at a gardening store, and today she is helping assemble gas trimmers to be sold. an employee from an earlier shift already assembled 7 trimmers, and diane can assemble 4 trimmers per hour. write an equation that shows how the total number of trimmers assembled, y, depends on the number of hours diane spends assembling them, x. y =

Explanation:

Step1: Identify base - number of trimmers

There are 7 trimmers already assembled.

Step2: Identify rate of assembly

Diane assembles 4 trimmers per hour. In x hours, she assembles 4x trimmers.

Step3: Form the equation

The total number of trimmers y is the sum of the initial 7 trimmers and the number of trimmers Diane assembles in x hours. So, $y = 4x+7$.

Answer:

$y = 4x + 7$
