Answer:
$1020
Step-by-step explanation:
Since 15% is taken away, the total price would be $1,020. This means that the sales price is 85% of the price.
I got 224. 7(4)^2 = 112 •2 =224
Find how much greater 20 is than 5
20-5=15
the % is of 5, so the percent is percent out of 5
20 is x% of 5 greater than 5
20=(x%)5+5
minus 5 both sides
15=(x%)5
divide both sides by 5
3=x%
percent means parts out of 100
x%=x/100
3=x/100
times 100 both sides
300=x
answer is 300%
B.)155
a1+d(n-1)
a1+d(6-1)=50
a1+5d=50
a1+d(11-1)=85
a1+10d=85
a1=50-5d
(50-5d)+10d=85
50-5d+10d=85
5d+50=85
5d=35
d=7
a1+7(6-1)=50
a1+35=50
a1=15
15+7(n-1)
15+7(21-1)
15+7(20)
15+140=155
Answer:
it's equal since they are opposites
