To the percentage of something do $45 times 0.3
0.3 represents the percent of discount
When you do that you should get $13.5
$13.5 just represents the amount you are going to take away from $45, so subtract 13.5 from 45
Answer:
D. $31.5
Answer:
x=2
Step-by-step explanation:
5(x+3)-2=13
5(x+3)=15
x+3=5
x=2
I guess the original function was
y = 5x (1)
y+Δy =5(x+Δx) (2)
(2) - (1) =
Δy = 5Δx
Δx →0, Δy/Δx →5
2/3 • 1/5 = 2/15
'of' always means multiplication.
