Problem
QUESTION 6 Use a proportion to solve the problem. Martin can paint \( 2200 \mathrm{ft}^{2} \) with 5 gal of paint. How many 1-gal cans does he need in order to paint a \( 25,000-\mathrm{ft}^{2} \) wall? 285 cans 64 cans 12 cans 57 cans
Solution
Step 1 ：\( \frac{2200}{5} = \frac{25000}{x} \)
Step 2 ：\( x = \frac{5 \times 25000}{2200} \)
Step 3 ：\( x = 56.8182 \)
