\bf \textit{circumference of a circle}\\\\
C=2\pi r\qquad 
\begin{cases}
diameter=d\\
r=radius=\frac{d}{2}\\
----------\\
C=78.5\\
\end{cases}
\\\\\\
 78.5=2\pi r\implies 78.5=2\pi \cdot \cfrac{d}{2}

solve for "d"

AfilCa [17]

Answer:

(A) Your friend will save $282.

(B) Your friend will get 23.5% off the original price of the mattress.

Step-by-step explanation:

We first need to find out the price of the mattress after the 15% discount. Our first step is to find what 15% of 1,200 is. We can do this by multiplying the two numbers.

1,200 x 15% -----> 1,200 x 0.15= 180.

15% of $1,200 is $180.

Next subtract $180 from $1,200, which equals $1,020. We can now apply the 10% off internet coupon.

1,020 x 10% ------> 1,020 x 0.10= 102.

10% of $1,020 is $102.

Next we subtract $102 from $1,020 and we get $918, the final price of the discounted mattress.

We subtract to see how much money the friend saved.

$1,200 - $918= $282.

We can get the percentage by dividing $282 by $1,200.

282 / 1200= 0.235 decimal form ----> 23.5%
