svlad2 [7]

Answer:

$63.36

Step-by-step explanation:

The home audio system costs $264 wholesale.

The system's price had been increased by 60 percent at the electronics retailer.

Consequently, the increased cost is 60/100x264=$158.40.

The audio system's total cost is now $422.40 (264 + 158.40).

Given that Lori received a commission of = 15% on $422.40, her commission is now (15/100) x 422.40

= $63.36

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.

Step-by-step explanation:

Let,

Cost of 1 dozen doughnuts = x

Cost of 1 dozen croissants = y

According to given statement;

7x+3y = 53 Eqn 1

x+5y = 35 Eqn 2

Multiplying Eqn 2 by 7

$77(x+5y = 35)\\x+35y=245\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(7x+35y)-(7x+3y)=245-53\\7x+35y-7x-3y=192\\32y=192$

Dividing both sides by 32

$\frac{32y}{32}=\frac{192}{32}\\y=6\\$

Putting y=6 in Eqn 2

$x+5(6)=35\\x+30=35\\x=35-30\\x=5$

A dozen of doughnuts cost $5 and a dozen of croissants cost $6.
