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
Hope this helps :)

Answer:
C
Step-by-step explanation:
Rate of change is the slope
Function A:
Slope = change in y/Change in x
= (9-3)/(3-0) = 6/3 = 2
Function B:
Clearly the slope is 3
(y = mx + c, m is the slope)
Rate of change of B is more than A
Answer:
Below
Step-by-step explanation:
To find the answers for the table, you must plug in each x value into the equation and get your y value:
x = -1
(-1^2)-(4*-1)-1
=
1+4-1
=
4
When x = -1, y = 4
x=0
(0^2)-(-4*0)-1
=
-1
When x = 0, y = -1
x = 1
(1^2)-(4-1)-1
=
1-4-1
=
-4
When x = 1, y = -4
x = 2
(2^2)-(4*2)-1
=
4-8-1
=
-5
When x = 2, y = -5
x = 3
(3^2)-(4*3)-1
=
9-12-1
=
-4
When x = 3, y = -4
I made a graph of this shown below.
I also created a table, that answrs your question below.
Hope this helps!
It's a prime number meaning only 1 and 67 are the only whole numbers that will give you 67
