Answer:
(11)
Step-by-step explanation:
If it varies directly, you need to find k, the constant of proportionality.
This is done by plugging the values in for x & y that are known.
y = kx
18 = k(5)
= k
Now solve for y when x is 11.
y = (11)
y = 39.6
Take the percent discount and flip it out of 100% so if the discount is 20% flip it to 80% then make that a decimal so .80 and multiply the original price by the decimal you found so 95*.80 and that's your sale price.
Answer:
2
Step-by-step explanation:
We can find the slope using the formula
m = ( y2-y1)/(x2-x1)
= ( 5-1)/( -1 - -3)
= ( 5-1)/( -1+3)
= 4/2
= 2
