Answer:
Step-by-step explanation:
Let M = total amount of money earned
M = 12x+8y
To make more than $190, the equation is:
190<12x+8y
Since Trevor is going to scoop ice cream for 20 hours, the equation is:
190<12x+8(20), which simplifies to 190<12x+160.
Isolate x to find the amount of hours that Trevor needs to tutor.
190-160<12x
30<12x
30/12<x
2.5<x
Trevor must tutor for more than 2.5 hours to make more than $190.
if im correct its 50 more of the original amount.
example: if i make 100 a day , im now making 150 a day
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
F(x)=x^2-4x+7
