Translate the statement into a formula.
The total monthly earnings, t, equal $7 per hour times the number of hours worked, h.

• t = 7 - h 

• t = 7 + h

• t = 7h

• t = 7

Translate the statement into a formula.
The total distance traveled, d, at a constant speed of 65 miles per hour is the product of the speedand the number of hours traveled, h.

• d = h + 65

• d = 65/h

• d = 65h

• d = 65 - h
