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 = <<7+4=11>>11.
The cost of the children's tickets is 11 × $3 = $<<11*3=33>>33.
The total amount of adults that went on both days is 5 + 2 = <<5+2=7>>7.
The cost of the adults' tickets is 7 × $4 = $<<7*4=28>>28.
The zoo made $33 + $28 = $<<33+28=61>>61 in total.
