3he cost of 5 cans of dog food is \( \$ 4.35 \). At this price, how much do 11 cans of do food cost? Explain your reasoning.

To determine the cost of 11 cans of dog food, we first find the price per can. The cost of 5 cans is \( \$4.35 \), so the price per can is \( \frac{4.35}{5} = \$0.87 \). Now, to find the cost of 11 cans, we multiply the price per can by the number of cans: \( 0.87 \times 11 = \$9.57 \). Thus, the cost of 11 cans of dog food is \( \$9.57 \). When dealing with ratios and unit prices, it's beneficial to simplify your calculations by finding a unit price first. This way, you reduce the chances of calculation errors and make your work more efficient! Common mistakes in these types of problems include forgetting to multiply by the correct number of cans or misplacing decimal points.
