Allison drove to work 18 days last month for a total of 230.4 miles driven if she has driven to work 21 days this month how many miles have sheet driven

Answer 1

We can set up a proportion to solve this problem:

days driven last month / miles driven last month = days driven this month / miles driven this month

18 / 230.4 = 21 / x

Cross multiplying, we get:

18x = 21 * 230.4

Simplifying, we have:

18x = 4838.4

Dividing both sides by 18, we find:

x = 4838.4 / 18 = 268.8

Therefore, Allison has driven 268.8 miles this month.
