Answer:
Brand A is the best buy.
Step-by-step explanation:
Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be 5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be 8.47/48 = $0.8 per pencil rounded up to the nearest tenth.Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.
80% of x = 32
80% × x = 32
.80x = 32
x = 32/.80
x = 40
80% of 40 games is 32 games.
The marked price of the ring given the cost as 8740 inclusive of 15% tax and discount of 5% is $7,283.3.
<h3>Marked price</h3>
- Cost of the gold ring = $8740
- Tax = 15%
- Discount = 5%
- Marked price = x
8740 = x + (15% of x) + (5% of x)
8740 = x + (0.15x) + (0.05x)
8740 = x + 0.15x + 0.05x
8740 = 1.20x
x = 8740 / 1.20
x = 7283.33333333333
Approximately,
x = $7,283.3

The answer is C. From the solution in the picture
Answer:
a= 
or 
Step-by-step explanation:
Equate the equation to zero
-9a+2=0
-5a-4a+2=0
5a(2a-1)-2(2a-1)=0
Write out the factors
(5a-2)(2a-1)=0
Then equate each factor to zero
5a-2=0 OR 2a-1=0
5a=2 OR 2a=1
a= OR a=
a= or
