Answer:
t = 6 hours
Step-by-step explanation:
D = r x t
1920 = 320t
divide both sides by 320:
t = 6 hours
Total number of hours = 15
Let the hours spent tutoring french be x.
Therefore hours spent on scooping ice cream = (15 - x)
Amount: Tutoring french is $15 an hour, total for x hours = 15x
For scooping ice cream it is $10 an hour 10*(15 - x) = 150 - 10x
To make more than $180
15x + (150 - 10x) > 180
15x + 150 - 10x > 180
15x - 10x > 180 - 150
5x > 30
x > 30/5
x > 6
So he needs to tutor more than 6 hours in order to make more than $180
