Question

Flying lessons on weekdays cost m dollars per hour. Flying lessons cost 1.2m dollars per hour. The expression
`9m + 3(1.2)m`represents the total dollar amount that Mayra spent on flying lessons. What does the 9m in the expression represent?

Answer 1

Data:

Weekdays: m dollars/hour

Weekend: 1.2m dollars/hour

`9m+3(1.2)m`

If (1.2m dollars/hour) is the cost in weekends, and (m dollars/hour) is the cost in weekdays.

Then, in the math expression the 9m represents the cost of the flying lessons Mayra take in weekdays.
