Answer:
c)
Step-by-step explanation:
y = mx +c
c is y-intercept. At y-intercept , x = 0.
So, from the table, c = -5
y = mx - c
Choose any point from the table and Plugin the values in the above equation.
(4 , 1.4)
1.4 = m*4 - 5
1.4+5 = 4m
6.4=4m
6.4/4 = m
1.6 = m
y = 1.6x - 5
5 1/2 = 5 5/10 and 1 1/5 = 1 2/10. 5 5/10 + 1 2/10=
6 7/10

Answer: $18</h3>
========================================================
Work Shown:
40% = 40/100 = 0.40
40% of 45 = 0.40*45 = 18
The sale price is $18. You save 45-18 = 27 dollars.
Note how 27/45 = 0.60 = 60%, meaning you got a 60% discount. Furthermore, note how 60% + 40% = 100%. So if you get a 60% discount, you still have to pay 40% of the original price.
