Answer:
42 men are in the dance recital.
Step-by-step explanation:
A.) If Lucy sells 1 necklace, her sales would equal to $15.99. Then her profit would be:
Profit = $15.99 - $3.38(1) - $5.57(1)
Profit = $7.04
The fraction of the sale price of the necklace in profit is denoted as x.
15.99x = 7.04
x = 704/1559
b.) This is the same as part (a) but in decimal form. Just simply divide 704 by 1559. The answer is 0.44
c.) If Lucy's sales is $223.86 and each necklace costs $15.99, then the number of necklaces sold is $223.86 ÷ $15.99/necklace = 14 necklaces
Her profit for the 14 necklaces sold would be:
$223.86 - $3.38(14) - $5.57(14) = $98.56
A = kdv^2 where A = amount oil d = distance and v = speed and k is a constant
so
30 = k*85*42^2
Now solve for k:-
k = 30 / (85*42^2) = 0.00020008
So when d = 26 and v = 54
Amount of oil A = 0.00020008 * 26*54^2
= 15.2 barrels
