Question

On the first day of a family road trip, Kai's family travels 365 miles.

On the third day, they travel 20% farther.

How many miles does Kai's family travel on the third day?

Answer 1

438 miles

Explanation:

You want to know the number of miles that is 20% farther than 365 miles.

Multiplier

Adding 20% to the first-day mileage causes its value to be multiplied like this:

365 + 0.20·365 = 365·(1 +0.20) = 365·1.2

Kai's family traveled 365·1.2 = 438 miles on the third day.
