trina is purchasing a new bike. the store is having a 20% off sale, and she has a 10% coupon. the original price of the bike is
$89.75. what is the final price?
2 answers:
We are given that:
i- The store is having 20% off sale
ii- Trina has a 10% coupon
Therefore, Trina will be having a discount = 20 + 10 = 30% of the bike's price
This means that:
Trina will pay 100% - 30% = 70% of the price
We are given that:
The original price of the bike = <span>$89.75
We now know that:
Trina will pay 70% of its price
Therefore:
Final price = 70% * </span>89.75 = 0.7 * <span>89.75
Final price = $62.825
Hope this helps :)</span>
We know the original price of the bike:
price_original=$89.75
In order to calculate the final price, we should calculate the following: original price-sale-coupon
The sale is 20%, which means: sale=20/100*$89.75=0.2*$89.75=17.95
The coupon is 10%, which means: coupon=10/100*$89.75=0.1*$89.75=8.975
The final price is: price_final=$89.75-17.95-8.975=$62.825

Step-by-step explanation:
Hi?
Answer:
Solution:
Given,
Radius(r) = 11 ft
C = ?
Now,

C = 2 × 3.14 × 11
= 70 cm
again,
C = 360°
angle = 315°
So,
C = 70 cm
or, 360° = 70 cm
or 1° = 70/360°
or 1° = 7/36
again ,
area = 7/36 × 315°
= 61.25 cm
