Sorry i have learnt it but i can remember how to do it
Answer:
option A is answer.
Step-by-step explanation:
Amount of interest earned for compounded monthly for $1 = 1.040742
Amount of interest earned for compounded quarterly for $1= 1.040604
Difference for $1 = 1.040742 - 1.40604
=0.000138
Difference for $7000 = $7000x0.000138
= 0.966
or $0.96
We can solve this system using elimination:
(x+y=24)3
3x+5y=100
3x+3y=72
-(3x+5y=100)
0x-2y=-28
y=14
We can then plug this back into one of the original equations:
x+14=24
x=10
We can check our answer by plugging this into both of the original equations:
10+14=24
24=24
3(10) + 5(14)=100
30+70=100
100=100
Therefore, there are 10 3-point questions and 14 5-point questions.
