Answer: $1200
Step-by-step explanation: Lets use the percent equation.
78 = 0.065 x t (Convert 6.5% to a decimal and t = total cost of camera.)
78/0.065 = 0.065t/0.065
t = 1200
So the total cost of the camera is $1,200
I have a question for you though, is this a question in your Envision Math book as a review for lesson 4-3?
