y = ( 3 * x ) - 2.
This is because the card costs for 3 $ and should be multiplied by the number of total cards she buys in that particular day. So 3 * x.
Now as she has got a 2$ off coupon, whatever the total is she gets 2 dollars off on that price. So we will subtract 2 at that time. FInally all this summed up would be equal to y.
Answer:
B is the correct answer.
Step-by-step explanation:
graph attached below, with red as the parent function (f(x)=3^x) and blue as the change (f(x)=3^x-8).
There were about 500 to 600 students that attended the University of salamanca by the end of the 14th century
First solve the return in each
price per unit
Return = number units sold x price
per unit
Return1 = 5000 units x Php 900
Return1 = php 4,500,000
Next is solve the other price per
unit
Return2 = number units sold x
price per unit
Return2 = (5000 + 1500 units0 x (
php 900 – 100)
Return2 = php 5,200,000
So the php 800 per unit will have
greater return
9×2=18. add the tow zeros like this 9×2=18+00=1,800
