Answer:
Step-by-step explanation:
Let x represent the number of hours that that he spent washing cars.
Let y represent the number of hours that that he spent landscaping.
In a week, he can work no more than 19 total hours. This means that
x + y ≤ 19- - - - - - - - - - - -1
Jacob is working two summer jobs, making $10 per hour washing cars and making $8 per hour landscaping. He must earn at least $170. This means that
10x + 8y ≥ 170 - - - - - - - - - -2
If Jacob worked 4 hours landscaping, it means that
x + 4 ≤ 19
x ≤ 19 - 4
x ≤ 15
Also,
10x + 8 × 4 ≥ 170
10x + 32 ≥ 170
10x ≥ 170 - 32
10x ≥ 138
10x ≥ 138/10
x ≥ 13.8
The minimum number of hours is 14
Answer:
Your welcome
Step-by-step explanation:
$8160 the hours would be 480
$680 the hours would be 40
$35,360 the hours would be 2,080
$36,720 the hours would be 2,160
We can do this easily. Since we know that the numerator is more than the denominator, we need to know by how much.
39-28=11; It's only 11 more, which means 11/28 would be the fraction and the whole number is 1.
39/28= 1 11/28
