[Question]A group of 5 children are taken to an amusement park. Only 3 of them were daring enough to get on the Ferris wheel which cost $5 per child. Everyone had a go at the merry-go-round (at $3 per child). On their way home, they bought 2 cones of ice cream each (each cone cost $8). How much did they spend altogether?
[Answer]3 children rode the Ferris wheel at $5 reach for a total of 3 * $5 = $15. 5 children rode the merry - go - round at $3 each for a total of 5 * $3 = $15. 5 children bought 2 cones of ice cream each at $8 per cone for a total of 5 * 2 * $8 = $80. In total, they spent $15 + $15 + $80 = $110. The answer is 110.
