Question

the entrance fee to the zoo is $3,and to get into the gardens is $2.A ticket to get into both is $4. One day 900 people were at the zoo and 700 in the garden.If 500 people visited only the zoo,what was the total amount of money collected that day

Answer 1

Is 900 the total that visited? If so, then if 700 in the garden, then 700-500 is the number that visited both and 900-700 is the number that visited only the zoo.

700(2) + 200(3) + 200(4) = ?
