Sally is running a sunblock factory and there is a machine to fill the sunblock the machines can fill 150 bottles an hour and each bottle takes 20 ounces of sunblock if sally runs the machines for 10 hours at least how many gallons will sally need to fill all the bottles

To answer this you will find the total amount of sunblock that can be filled in 10 hours. Then we will convert the number of ounces to gallons.

1. 150 bottles per hour for 10 hours is 150 x 10.

1500 bottle can be filled.

2. 1500 bottles at 20 ounces per bottle is 1500 x 20

30000 ounces of sunblock

3. There are 128 fluid ounces in each gallon so take 30000 ounces and break it into groups of 128 ounces.

30000/128 = 234.375 gallons

You will need at least 235 gallons of sunblock.
