Answer: I believe his earnings would be 187$ once he teaches 7 classes.
Step-by-step explanation:
$187-$68=$111
17 x ? = 119
(take the 17$ which is the amount of money he'll earn each class and divide by 111. as seen below:
$111/17$=$6.5 (round to $7)
(you then plug in the 17 for 7 x ? = 119)
7x17=119
now you have to add the 68$ that he will get per month.
119+68=187
then you get 187$ which he had spent on the certificate
Cos to 2 decimal places is -0.90

Answer:
$12000
Step-by-step explanation:
P=CRT
C=cost
R=rate
T=time
P=3000 x 8 x 50/100= $12000
We would subtact 3 from both sides allowing the equation to simplify to -8c=32
We would then divide both sides by -8 to equal -4
The final answer C=-4
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run. 
From the picture, I have drawn the rise over run, which is 
, which is also 1.
Slope: 1
Hope this helped.
