a. If Enguun tutored for 12 hours this month, how much money did she earn this month?
b. If Enguun tutored for 19.5 hours last month, how much money did she earn last month?

Answer 1

she earns $204 this month

she earned $33.15 last month

Explanation:

Enguun earns $17 per hour tutoring student-athletes at Brooklyn University.

Enguun tutored for 12 hours this month

1 hour tutoring rate is $17

we need to find out how much she earn for 12 hours

rate per hour times the number of hours tutored

12 times 17=204

she earns $204 this month

(b) Enguun tutored for 19.5 hours last month

rate per hour times the number of hours tutored

17 times 19.5=33.15

she earned $33.15 last month

Answer 2

a. Earnings of Enguun for 12 hours this month (G)

G = 204 dollars

b. Earnings of Enguun for 19.5 hours last month (G)

G = 331.5 dollars

Explanation:

Nomenclature

G: Total earnings of Enguun in dollars

E: Enguun's earnings for 1 hour of tutoring (dollars/hour)

n: number of hours that Enguun tutored per month (hour/month)

Formula

G = E*n

E = $17 per hour = 17 dollars/hour

Problem development

a. Earnings of Enguun for 12 hours this month

n = 12 hours

G = E*n

`G= 17(dollars)/(hour) * 12 hour` : We eliminate hours

G = 204 dollars

b. Earnings of Enguun for 19.5 hours last month

G = E*n

G = 17 * 19.5

G = 331.5 dollars
