Answer: -112
Step-by-step explanation:
Given: Rate of lost money on an investment = $4 per day.
Since 1 week = 7 days
So, Amount of money she lost in 1 weeks = $ 4 x 7 = $28
⇒ Amount of money she lost in 4 weeks = $ 28 x 4 = $112
Since in integers, a loss is represented by negative integer.
So, Mrs. Rockwell lost $112 after 4 weeks which is represented by "-112" integers.
To get the x-intercept, we simply set y = 0 and solve for "x".
now, we have the slope and the y-intercept, well, let's plug those two in the slope-intercept form, reason why is called that anyway,
This can be solved by using a simple algebraic equation.
For example, in the first column, Caleb worked 5 hours. We do not know how much he makes per hour, so let that be x. He earned a total of $36.25, so the equation can be written as 5x=36.25.
Divide by 5 on both sides, and you get x= 7.25
He earns $7.25 per hour of work.
Repeat this for all the workers:
Jeremy: 7.5x=65.25
x= $8.70
Maria: 4.25x=34.00
x= $8
Rosa: 8x=54.00
x= $6.75
Jeremy has the greatest hourly rate
Answer=7 minivans
45/7=6.4
since you can't have 0.4 minivans, we round up 6.4 to 7
