Question

A 37 inch tv sells for $400. This is a $45 less than five times the cost of a 19 inch tv. Find the cost of the 19 inch tv.

Answer 1

Answer:

A 19 inch tv cost $89

Step-by-step explanation:

37 inch tv : 400 = 5x - 45

19 inch tv : x

We have the equation:

5x - 45 = 400

5x = 445

x = 89
