Answer:

gain = 0

% = 0

Step-by-step explanation:

Profit

He sells one for a profit of 25% That means he sells one of them for 100% + 25% = 125%

₹1500 * 125/100 = ₹187500/100 = ₹1875

Loss

Here he sells it for 25% less than the selling price he wanted.

100% - 25% = 75%

₹1500 * 75/100 = ₹112500/100 = ₹1125

Discussion

He should make ₹1500 + ₹1500 = ₹3000 without either profit or loss.

What he actually accomplishes is ₹1125 + ₹1875 = ₹3000

So he has a net gain (loss) of 0.

The % is 0

The amount ofmoney is in the ratio 8:3 if the first amount is 9.92 what is the second amount?

BARSIC [14]

Answer:

The second amount is 3.72

Step-by-step explanation:

Given

$First : Second = 8 : 3$

$First = 9.92$

Required

Find Second

$First : Second = 8 : 3$

Substitute 9.92 for First

$9.92: Second = 8 : 3$

Express as fraction

$\frac{Second}{9.92} = \frac{3}{8}$

Multiply both sides by 9.92

$9.92 * \frac{Second}{9.92} = \frac{3}{8}*9.92$

$Second = \frac{3}{8}*9.92$

$Second = 3.72$

Alex is making puppets for a show. He bought all the string needed for $125. It costs $18 for the remaining materials to make ea

Alexus [3.1K]

Alex bought all the string needed for $125.

It costs $18 for the remaining materials to make each puppet.

So if we closely observe then we see that here $125 is the fixed cost because its not going to change with number of puppets.

And the variable cost is $18.

In this case we can model a Total cost function C(x) for for x number of puppets as below

$C(x)=125+18x\\ \\ \text{Here x is the number of puppets}\\ \\ \text{Since in our case the number of puppets is 50 so replace x by 50 we get }\\ \\ C(50)=125+18*50\\ \\ C(50)=125+900\\ \\ C(50)=1025 \ dollar.$

The total cost to make 50 puppets=$1025
