Explanation:
It is given that the original cost of cards is y. It is also given that cards was on sale of 13% and the tax in the country is 8%.
There is a sale of 13% it means the prices are 13% less.
13% of y =
The price of cards after discount is

The price after discount is 0.87y.
It is given that the tax in the country is 8%.
The amount of tax on the cards is calculated as shown below,

The price after discount is is calculated as shown below,

Therefore, the correct option is option (B) 1.08(0.87y).
Answer:
B.) 80 cans, 20 brushes
Step-by-step explanation:
Let the cans of paint be represented by variable <em>p</em> , and brushes by variable <em>b</em>
The first equation would be ; p + b = 100
p = 100 - b
The second equation would be;
8p + 12b = 880
Replace p in the equation by (100-b);
=8(100-b) + 12b =880
=800 - 8b +12b = 880
= subtract 800 from both sides to get;
4b = 880-800
4b = 80
divide both sides by 4 to solve for b;
b= 80/4
b = 20
If p + b = 100, then p+20 = 100
p = 100-20
p = 80
Therefore, they sold 80 cans of paint and 20 brushes
