Host A: 60+13.25h
Host B: 75+11.5h
60+13.25h =75+11.25h
subtract 11.25h from each side
60+2h = 75
subtract 60 from each side
2h = 15
divide by 2
h = 7.5
at 7.5 hours the two hosts will charge the same
5x=5-25y => x = 1 - 5y;but, 3x-2y=6 => 3( 1 - 5 y ) - 2y = 6 => 3 - 15y - 2y = 6=>-17y = 3 => y = -3 / 17;x = 1 - 5 * ( -3 / 17 ) => x = 1 + 15 / 17 => x = 32 / 17.
Remark
First of all, you should notice that the number you want must end in 5 to get a remainder of 5. That's because your divisors all end in 0.
Step One
Factor the 3 divisors
40: 2 * 2 * 2 * 5
50: 2 * 5 * 5
60: 2 * 2 * 3 * 5
Step Two
Using these factors, find the LCM
There are 3 twos, 1 Three, and 2 fives.
The LCM is 8*3*25 = 600
Step Three
Find the first number over 1000 that is divisible by 600. That should be 1200 which is 600 * 2
So the answer to your question is 1205
Answer:
The selling price after the markup is $1.82
Step-by-step explanation:
$1.40 * .30 =
Multiply $1.40 times .30 (which is same as 30%)
$1.40 * .30 = $0.42
Add $1.40 and $0.42
= $1.82
Hope this helps.
