For his birthday, Mr. Robin and four of his friends went to a Math museum to learn about new intergalactic math. They each got a ticket for $12.00 and each bought the same calculator at the gift shop. If Mr. Robin spent $110 for the group's tickets and calculator, how much did each calculator cost? Write and solve an equation to describe this situation.

$10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for each

If each one of them bought a calculator then the total spendings are

Suppose the cost of each calculator is

Cost per person is given by  

For the group, it is

Equate this to total spendings

thus, the cost of each calculator is

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
