Bad White [126]

Answer:

<h2>12.1% profit</h2>

Step-by-step explanation:

Given data

total eraser= 87

cost =$3 each

Total cost of eraser= 87*3= $261

she sold 63 at $3.5

1. sales made for the 63= $220.5

Total sales made = 220.5+72=$292.5

her profit= sales-cost

profit= 292.5-261=$31.5

therefore the percent profit is

=31.5/261*100

=0.12*100

A chemist has 10% and 40% solutions of acid available. How many liters of each solution should be mixed to obtain 120 liters of
kaheart [24]

Answer:

100 liters of  10% solution is used and 20 liters of  40% solution is used

Step-by-step explanation:

Let "X" amount of 10% solution is used. Then the amount of 40% solution used is equal to 120-X

Now

10% of X + 40% of (120-X) = 15% of 120

On solving the above equation, we get

0.1 X + 0.4 (120-X) = 0.15 *120\\0.1 X + 48 -0.4X = 18\\0.3 X = 30\\X = 100liters

Amount of 40% solution used  = 120 -X = 120-100 = 20 liters

100 liters of  10% solution is used and 20 liters of  40% solution is used
