9. A television regularly costs $180, but it is on sale for 40% off. There is a 5% sales tax on the sale price. How much does the television cost after
the discount and sales tax?
A $75.60
B.$103.00
C. $113.40
D. $145.00

C $113.40

Step-by-step explanation:

100%-40%=60%

$180x60/100

=$10800/100

=$108

100%+5%(tax)=105%

$108x105/100

=$11340/100

=$113.40 (C)

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
