Answer: third option: old pice was $170; new price is $159.12
Explanation:
1) Formula given:
Selling price = original cost + mark up value
2) Old price = original cost + 25% (original cost)
Old price = $136 + 35% ($136) = $136 + 0.25×$136 = $136 + 34 = $170
3) New price = original cost + 17% (original cost)
= $136 + 17% ($136) = $136 + 0.17×$136 = $136 + $23.12 = $159.12
The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>
Solution
Let x = registration fee
y = cost/downloads
Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50
Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95
for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5
Paybeginning $1,032 - $150 = $882.56* 1.00938 = $ 890.84
Pay end $1,032.56 * 1.00938 = $1042.25- $150 = $892.25
The difference is in interest in the first month 892.25−890.25=2
Note: 11.25 / 12 = 0.00938 interest per month
I’m pretty sure this is right. if you add -3 and 7 you get 4 and if you multiply the two, you get -21. hope this helped!
