It takes Chris 10 minutes to drive, so the latest time he can leave home for work would be 7:50 a.m.
Answer:
A) X + Y = 12
B) 10Y + x = 10x + Y -18
B) 9Y = 9x -18 multiplying A) by -9
A) -9Y = 9x - 72 adding A and B we get
0 = 18x -90
x = 5
The number is 75
Double-Check
7 + 5 = 12
75 -57 = 18
Step-by-step explanation:
In order to calculate the equivalent discount, consider the principle number is 100,
Then, 100 - 100 * 0.20 = 100 - 20 = 80
Now, 80 - 80 * 0.15 = 80 - 12 = 68
So, Total discount would be: 100 - 68 = 32%
Hope this helps!
