1. COST Mr. Rivera wants to purchase a riding lawn

mower, which is on sale for 15% off the marked price.

The store charges sales tax 6.5% on all sales. Write a

function p(x) that represents the price after a 15%

discount. Write a function t(x) that represents the total

cost with sales tax. Write a composition of functions that

represents the total cost of a riding lawn mower on sale.

How much will Mr. Rivera pay for a riding lawn mower

that has a marked price of $3000?

a) 0.25x times 3. (could be wrong on equation.)

b) 2.25 pound of dark chocolate. (can i eat all the chocolate? plz? anyway, again, could be wrong, but i hope im right. all the chocolate together should be 5.25 pounds)

step-by-step explanation:

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
