A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product. How many gallons were made in all?

So, total gallons were made in all = 9.31 gallons

Step-by-step explanation:

We are given

A scientist repeated an experiment three times, making 1.42, 3.81, and 4.08 gallons of a new product

so,

first experiment = 1.42 gallons

Second experiment = 3.81 gallons

Third experiment = 4.08 gallons

now, we can find total gallons

total gallons = first experiment + second experiment + third experiment

total gallons = 1.42 gallons + 3.81 gallons + 4.08 gallons

total gallons = 9.31 gallons
