Answer:
Step-by-step explanation:
a ) Let the volume required be v .
v x .8 + 500 x .3 / ( v + 500 ) = .7
.8 v + 150 = .7 v + 350
.1 v = 200
v = 2000 mL
b )
Let the volume of solution A required be v . The volume of solution of B required will be 100 - v
v x .8 + ( 100 - v ) x .3 / 100 = .5
.8 v + 30 - .3 v = 50
.5 v = 20
v = 40 mL
volume of solution B = 60 mL .
c )
It is not possible because 90 % is more than 80 % the concentration of solution A . Any mixture will have concentration less than 80 % .
volume of solution B = 60 mL
Answer:
If total Revenue is $3000, Cost of Goods is $1500, and total Selling Expense is $500Question: what is the Profit for the business=> The total revenue is 3 000 dollarsThe expenses:=> 1 500 dollars for gold's costs=> 500 dollars for selling expenses.Now, let's add the expenses and subtract it to the total earnings=> 1 500 dollars + 500 dollars = 2 000 dollarsNow, let's subtract:=> 3 000 dollars - 2 000 dollars = 1 000 dollars. Thus, his profit is 1 000 dollars
