X over 49.5 and 20 over 100 then you cross multiply and you get 100x is equal to 990 you divide 100x and 990 both by 100 and get x and 9.9 then you have 50 seniors a month that you give the discount to so you multiply 9.9 by 50 and get 495 so the total discount you give on an average monthly basis is $495.00 Hope this helped
Answer:
2x + y = 18
y = 4x - 12
x = 5, y = 8
Step-by-step explanation:
x = 1st number
y = 2nd number
We can use the substitution method as we know what 'y' equals; that value will get plugged in for 'y' in the first equation as follows:
2x + 4x - 12 = 18
6x - 12 = 18
6x = 30
x = 5
y = 4(5) - 12 which is 20-12 or 8
y = 8
Answer:
Market Price = MP
Cost Price = CP
P1 = (MP - 10%) - CP = Rs8
- CP = Rs8 - 0.90% MP
CP = 0.90 MP - Rs8
P2 = MP - CP = Rs20
- CP = Rs20 -MP
CP = MP - Rs20
0.90 MP - Rs8 = MP - Rs20
- 0.10% MP = - Rs12
0.10% MP = Rs 12
MP = Rs120p
CP = MP - Rs20 = Rs120 - Rs20 = Rs100.
The cost price of the item is Rs100.

In order to find this you have to replace any x with zero therefore we will have
3 - (2*0) => 3-0 = 3
so the answer is 3
