Trevor tutors french for $12 an hour and scoops ice cream for $8 an hour. he is going to work 20 hours this week. at least how many hours does he need to tutor to make more than $190? let x equal the number of hours he tutors and y be the number of hours he scoops ice cream. at least how many hours does trevor need to tutor to make more than $190? express your answer as a decimal number.

Hours He will work in this Week=20 hours.

Number of Hours he will Teach=x

Number of Hours He will Eat icecream=y

We know

x+y=20

x=20-y (Equation 1)

Teaching French=$12

Eating Icecream=$8

Let He Total Money he Earn from Teaching.

=12×Number of Hours he work

=$12x

Eating Icecream=$8

Total money spent=$8y

But Total Money=$190

MEANS

$12x+$8y=$190

12(20-y)+8y=190

240-12y+8y=190

-4y=190-240

-4y=-50

y=50/4

y=12.5

We know x+y=20

x+12.5=20

x=20-12.5

x=7.5 hours

MEANS He have to teach At least =7.5 hours.To make $190

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
