Ariana bought 5 dozen pears at $36 per dozen . She discovered that 7 were rotten and she sold the rest at $4.50 each . Calculate

GrogVix [38]

Step-by-step explanation:

1 dozen = 12 pears

12 pears = $36

1 pear = 36/12 = $3

Total Cost of Pears = No. of pears x price of 1 pear

= (5x12) x 3

= 60 x 3

= $180

Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)

= $4.50 x (5x12-7)

= $4.50 x 53

= $238.50

Profit/Loss = Sale of Pears - Total Cost of Pears

= $238.50 - $180

= $58.50

Ariana made a profit of $58.50.

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

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

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

$Second = 3.72$
