Answer:
Step-by-step explanation:
A grocery store has a 13%-off sale on all bread.
Let b represent the original price of a loaf of bread.
This means that the amount by which the price of bread was reduced would be
13/100 × b = 0.13 × b = 0.13b
The new price for the loaf of bread would be
b - 0.13b
you decide to purchase 6 loaves of bread. The expression would be
6(b - 0.13b)
Expanding the expression, it becomes
6b - 0.78b
To calculate the mean of a set of numbers and them all together and divide by the amount of numbers.
Example:
Find the mean of 12, 25, 36.
12 + 25 + 36 = 73
73 / 3 = 24.33
Our mean is 24.33.
Answer:
$4.40
Step-by-step explanation: First you divide 73.20 by 6 to get 12.2. Thats how much each costs with tax. Then you have to take tax off so 12.2-7.80=4.4. So $4.40.
Step-by-step explanation:
7(x-2)+3 (x+2)=5 (x-6)
- 7x-14+3x+6=5x-30
- 10x-8=5x-30
- 10x-5x=-30+8
- 5x=-22
- x=-22/5
