Question

Naomi and Claire are painting a mural. Naomi paints 2 square feet per hour and has already painted 16.5 square feet.

Answer 1

4.5 hours We can sum up the information in the question with two equations: y = 2x + 16.5 y = 4x + 7.5 Where y represents the total area painted by each person and x represents the time. These equations are in the form y = mx + b where m is the rate and b is the value at x = 0.
