Answer:
Question 1
<u>Given</u>
<u>Use formula and solve for x:</u>
- SP = CP + P
- 144 = x + (20% of x)
- 144 = x + 0.2x
- 144 = 1.2x
- x = 144/1.2
- x = 120
Cost price is N 120
Question 2
<u>Given</u>
- SP = 1000
- P = -20% (negative because of loss)
- CP = x
<u>Use formula and solve for x:</u>
- SP = CP + P
- 10000 = x - (20% of x)
- 10000 = x - 0.2x
- 10000 = 0.8x
- x = 10000/0.8
- x = 12500
Cost is N 12500
Answer:
answer C
Step-by-step explanation:
The answer is 5 ounces. We can tell this by subtracting 0.32 from 1.16 and then dividing the product (0.84) by 0.21. This should give you 4, but then you have to remember that you subtracted the first ounce that costs 0.32, so when you add it back, you should have an answer of 5 ounces.
2x-3y=4
x+4y=-9/*(-2)
2x-3y=4
-2x-8y=18
-11y=22/:(-11)
y=-2
x+4*(-2)=-9
x-8=-9
x=-1
I hope this helped.
The anwser would be C. trust me i just took this test
