Question

A caterer made an ice cream punch by combining fruit juice that cost $2.25 per gallon with ice cream that costs $3.25 per gallon. How many gallons of each were used to make 100 gal of punch costing $2.50 per pound?
-Thank you!

Answer 1

2.25x + 3.25(100-x) = 2.50 * 100

now convert $/gal to $/lb.
