2. 7 hours on Wednesday, 6 hours on Thursday, and 9 hours on Friday. His gross pay for all three days was $196.90

3.hourly rate of $11.28 per hour worked 46 hours last week. She works overtime for hours exceeding 40 hours in a week. She is paid overtime at a rate of time and a half. What was her gross pay last week?
$11.28 x 40 = $451.20 ---normal 40 hours paid
46 - 40 = 6 (6 hours over time)
11.28 + 11.28/ 2 = $16.92 (overtime pays a rate of time and a half)
6 * $16.92 = $101.52
$451.20(40hours) + $101.52(6hours overtime) = $552.72
answer: her gross pay last week was $552.72
4. Paul received a $15 tip on a meal that cost $120. What percent of the meal cost was the tip?

$720 + $ 130 = $850
answer: her gross pay was $850
Answer:
1.8
Step-by-step explanation:
To do this, you need the slope formula
y^2 - y^1 over
x^2 - x^1
x^1 y^2 x^2 x^1
( 5, 11) (-5 -1)
-7 - 11 = -18
-5 -5 = -10 (divide) = 1.8

Your answer is B) -5/6.
We can find this using the formula (y2 - y1)/(x2 - x1) and substitute in the coordinates:
(-2 - 3)/(5 - -1) = -5/6
I hope this helps!
1) <span>x + 24=95
2) 1 / 5x = 10
5x = 10/1
5x = 10
x = 10/5
x = 2
3) b/5 + 15 = 45
b = 5(45-15)
b = 150
