Jerry paid $135.04 after tax for $125.62 worth of groceries. What is the sales tax. rate, to the nearest tenth of a percent?

135.04 - 125.62 = 9.42

9.42/125.62=0.07498805

0.07498805 X 100 = 7.49880592

sales tax = 7.5%

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.
