To find the number of square feet the painter can paint in 7 hours, we can set up a proportion.
If the painter can paint 375 square feet in 3 hours, we can set up the proportion:
375 square feet / 3 hours = x square feet / 7 hours
To solve for x, we can cross multiply:
3 * x = 375 * 7
3x = 2,625
Dividing both sides by 3, we find:
x = 875
Therefore, the painter can paint 875 square feet in 7 hours.
