On Monday a group of 7 children and 5 adults went to the zoo. On Tuesday a group of 4 children and 2 adults went as well. Child tickets cost $3, and adult tickets cost $4. How much money did the zoo make in total for both days?
The total amount of children that went on both days is 7 + 4 = <T>add(7, 4)=11
The cost of the children's tickets is 11 × $3 = $<T>multiply(11, 3)=33
The total amount of adults that went on both days is 5 + 2 = <T>add(5, 2)=7
The cost of the adults' tickets is 7 × $4 = $<T>multiply(7, 4)=28
The zoo made $33 + $28 = $<T>add(33, 28)=61 in total.
