Jj sell tablets at a store. he earns $180 a week plus$15 for ever tablet he sells. jj earns $315 last week. write a equation that can be used to determine the number of computers jj sold last week. how many was sold

so Jj earns a flat rate of 180 per week and an extra 15 per tablet he has sold

so what we need to do is subtract his flat rate(180) from his total(315)

315

-180

135 So now we know how much money Jj has earned from selling tablets. But we still need to create an equation and find out how many he has sold.

So we know he get $15 per tablet so 135÷15=9

now we know he has sold 9 tablets

Bu what is our Equation?

well, what were the steps?

TP = total pay

FR= Flat rate

C= Computer profit

PPC= price per computer

#C = number of computers

#C = TP-FR=C C÷PPC=#C

can we simplify this further?

#C = C÷PPC

lets do this:

#C= x

C= y

PPC= z  

So:              (X = Y÷Z)

Step-by-step explanation:

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
