A group of friends walked into Juju’s Juice Bar ordered a glass of fruit juice each. They spent a total of $94. Some of them ordered mango juice, which sells for $5 a glass, while others asked for pineapple juice, at $6 a glass. If $54 was spent on pineapple juice, how many people were in the group?
The amount spent on mango juice is 94 - 54 = <T>subtract(94, 54)=40 dollars
Dividing the 40 dollars by the cost of a glass of mango juice gives us 40/5 = <T>divide(40, 5)=8.0 people
Since a glass of pineapple juice goes for $6, the number that ordered is 54/6 = <T>divide(54, 6)=9.0 people
Adding both numbers gives a total of 8 + 9 =<T>add(8, 9)=17 people
