If 12 dozen were bought for $90 that means each CD was bought at the price of $0.66
If he sold all 60 of the CD's for 5 for $12, he'd make $144.
Subtract the income by the original buying price to find his profit. $144 - $90
The peddler made $54 profit.
Answer:
= -3i + (3/4+2i) - (9/3+3i)
= (3/4 - 9/3) + (-3 + 2 -3)i
= -9/4 -4i
Answer:
y=-9
Step-by-step explanation:
If x equals 2, then we can substitute that into the equation, resulting in the equation 2*2-2y=22
We can solve for multiplication first:
4-2y=22
Then we can subtract four on both sides, canceling out the four on the left side:
-2y=18
Now to isolate y, we divide both sides by -2, resulting in the solution:
y=-9
Hope this helps!
Answer:
8/45
Step-by-step explanation:
1x8 is 8 and 5x9 is 45
Answer:
<u><em>1080</em></u> for the last one
Step-by-step explanation:
<em>40*12=480*2=960+120=</em><u><em>1080</em></u>
<em>12/4=3months 40*3=120</em>
The first one is 3
<em>1/2 + 1/4 = 3/4 </em>
<em>3/4 + 1/8 = 7/8</em>
<em>7/8 of 24 is 21</em>
<em>24-21= </em> <u><em>3</em></u>
