Answer: Second option is correct.
Step-by-step explanation:
Let the original price of chair be 'p'.
Number of chairs = 4
Discount rate = 25%
So, Amount of discount would be
So, Cost of each chair after discount would be
So, Cost of all 4 chairs would be
Hence, Second option is correct.
We need to know about the system of equations to solve such problems.
<h2 /><h2>Given to us </h2>- Sonji went to a sandwich shop for lunch with 8 of her friends.
- Part of the group ordered only a sandwich for $5, and the rest of the group ordered a combo for $8.
- The bill for all 9 people totaled $66.
Let's assume that the number of sandwiches ordered is x and the number of combos ordered is y.
<h2>Total Orders</h2>Given that the group of people was of 9 people, therefore, a total of 9 orders must be made.
Total number of orders = number of sandwiches ordered + number of combo ordered
total bill of the group
=(number of sandwiches ordered x cost of a sandwich ) + (number of combos ordered x cost of a combo)
Hence, we got the two equations of the system.
