Answer:
Step-by-step explanation:
Selling price for the shop = 63 + 21 = $84
As given,
Selling price for the shop = 150% of cost price of the shop
∴ 84 = 1.5 * Cost price
∴ Cost price = $56
Profit earned by bike shop = Selling Price - Cost price = 84 - 56 = $28
Answer:
$58.80
Step-by-step explanation:
Area = Length * Width square frame length & width will be the same
√196 = 14 inches
196 = 14 * 14
196 = 196
14 inches * 4 sides = 56 inches total needed for frame
Cost:
56 inches * $1.05 = $58.80
Let x be the amount of the 30% alcohol and let y be the amount of 5% alcohol.
We want the total amount to by 25 gal, then we have:

We also want the resulting mix to be 25% alcohol, this is 0.25 in decimal form; also we know that the first type of alcohol is 30% and the second is 5%, then we have:

Hence we have the system of equations:

To solve the system we solve the first equation for y:

then we plug this value of y in the second equation:

Once we have the value of x we plug it in the expression we found for y:

Therefore, the mixture will have 20 gallons of 30% alcohol and 5 gallons of 5% alcohol.
