Kevin uses a coupon for 75% off one item. He only pays $3.00 for a train set. How much money was the train set originally?

$12

Step-by-step explanation:

$3.00 is 25%

what about 100%

3.00×100=300÷25= 12.00

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
