Mr. Smith had 33 dozen cans. He sold 340 of them at $15 each. He sold the remaining cans at a discount of 20% each. How much money did he collect from selling the cans?
$

Mr. Smith collects $5748 from selling the can.

Step-by-step explanation:

Given total number of cans =  

Selling price of one can = $15.

Now remaining number of cans = total number of cans - sold number of cans =

For remaining number of cans he gives a discount of 20% each,

∴ Selling price of one can =  

∴ Selling price of 54 cans =  

So total money he earns =  .

Thus Mr. Smith earns $5748 by selling the cans.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
