Answer:
1)86
2)102
3)118
4)134
Step-by-step explanation:
1) so we know that the photographer started off with 86 photographs and has been uploading 16 each month since then
so in month 1 she would have 86
in month 2: 86+16=102
month 3: 102+16=118
month 4: 118+16=134
you could also use the expression
y=16x+70
how to get this equation: get slope(16) by subtracting p coords and m coord
substitute slope in slope intercept form
y=16x+b
insert in a coordinate pair(1,86)
86=16+b
b=70
hence y=16x+70

159.60
Step-by-step explanation:
If Joel gets 20% off, he still has to pay (100-20) or 80%
The cost of the tablet is now 190 * .80
Then he has to pay 5% sales tax.
The tax is the prices times 5% plus the original price
190 *.80 *(1+.05)
or 190 *.80 *(1.05)
Instead of adding the sales tax, he subtracted the sales tax.
The total he needs to pay is
190 *.80 *(1.05)
159.60

Answer:
Coach pug charges $45 only one time, and an additional of $20 per session.
So if you take x sessions, the total cost will be:
c(x) = $45 + $20*x
Dr. Doberman charges only $30 per session, then the cost for x sessions will be_
d(x) = $30*x
Now, which one is better for you?
We need to see the value of x such that:
d(x) = c(x)
$30*x = $45 + $20*x
$30*x - $20*x = $45
$10*x = $45
x = $45/$10 = 4.5
This means that if you take 4 sessions or less, is better the Dr. Doberman, because in this case we do not have an y-intercept.
If you want to have 5 sessions or more, is better Coach Pug, because the slope of the equation is smaller, so the costs for larger values of x will be smaller.
The answer would be 369.75
