11. The price of a new pair of True Religion
jeans is marked down
from $159.99 to $39.99.
What percentage was
taken off?

The percentage which was taken off = 75%    

Step-by-step explanation:

Using the formula

Percentage Decrease = [ (Initial Value - Final Value) / |Initial Value| ] × 100

                                     = [(159.99 - 39.99) / (159.99)] × 100

                                     = [120 / 159.99] × 100

                                     = 0.75 × 100

                                     = 75%

Therefore, the percentage which was taken off = 75%

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
