Raphael went to the store and bought 2 1/2 pounds of chicken for 9:00. At this rate, how much would it cost for 1, 2, and 3 pounds of chicken?

To find the cost for 1 pound of chicken, you can divide the total cost of 2 1/2 pounds by 2.5 (since 2 1/2 is equivalent to 2.5).

Cost of 1 pound of chicken = $9.00 / 2.5 = $3.60

To find the cost for 2 pounds of chicken, you can multiply the cost of 1 pound by 2.

Cost of 2 pounds of chicken = $3.60 x 2 = $7.20

To find the cost for 3 pounds of chicken, you can multiply the cost of 1 pound by 3.

Cost of 3 pounds of chicken = $3.60 x 3 = $10.80

Therefore, the cost for 1, 2, and 3 pounds of chicken would be $3.60, $7.20, and $10.80 respectively.
