Question

Sally is running a sunblock factory and there is a machine to fill the sunblock bottles 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 will sally need to fill all of the bottles

Answer 1

(150 bottles/h)*(10 h)*(20 oz/bottle) = 30,000 oz . . . . sunblock to fill 1500 bottles

Answer 2

Number of bottles the machine can fill in one hour = 150

Number of bottles machine can fill in ten hours = 150*10 =1500 bottles

Quantity of sunblock in one bottle = 20 oz

Quantity of sunblock in 1500 bottles = 1500 *20 = 30000 oz

Answer : Sally needs at least 30000 oz of sunblock to fill 1500 bottles of sunblock in 10 hours by the machine.
