Question

Adsilla and Carlos volunteer to fill gift boxes for soldiers serving overseas. Both work at a constant rate. They work together for 4 hours and fill 108 boxes. Adsila fills 11 boxes every hour. How many boxes does carlos fill every hour?

Answer 1

`Carlos = 16` per hour

Explanation:

Given

`Total = 108\ boxes`

`Hours = 4`

`Adsila = 11\ boxes\ per\ hour`

Required

Determine the unit rate of Carlos

First, we need to calculate the total boxes filled by Adsila.

If Adsila gets 11 in 1 hour.

Then Adsila get 4 * 11 in 4 hours

`4 * 11 = 44\ boxes`

Next, we calculate number of boxes left.

`Left = 108 - 44`

`Left = 64`

This is yhe number of boxes filled by Carlos.

Recall that they worked for 4 hours each.

Hence:

`Carlos = (64)/(4)`

`Carlos = 16`
