Recipe calls for 4 cups of sliced almonds. You purchase a 2 pound bag for \$24.20. Each bag contains 9.5 cups of almonds. What is total cost for the almonds? Thank you in advance. Last edited by skipjack; February 24th, 2017 at 11:37 PM.

The total cost is \$24.20, but I don't think that's what you mean.

If do you mean, what is the cost of 4 cups? Then, calculate the cost of 1 cup almonds: $\dfrac{19}{24.20}=\$0.78$(cost of 1 cup almonds) $0.78\times 4=\$3.14$(cost of 4 cups almond)

Cost per cup is $\dfrac{\$24.20}{9.5 \text{ cups}} \approx \$2.55$ per cup Last edited by skipjack; February 25th, 2017 at 04:49 AM.

Cost of 4 cups of almonds = (4/9.5) * \$24.20 = \$10.19.

Teacher who made that up must have been "nuts" ! Just noticed that all problems posted by Tongass are about recipes...

Thanks @skeeter First, we calculate the cost of 1 cup almonds, i.e., $\dfrac{24.20}{9.5}≈\$2.55$ per cup So, cost of 4 cups almonds will be: $\$2.55×4=\$10.20$(cost of 4 cups almonds)
