Answer: 1309.24 I used calculations and I think this is right
Step-by-step explanation:
Answer:
change the order, so the terms line up
20g+15m=300
g+m=17
multiply the second equation by 20, so the 20g and -20g can cancel out
20g+15m=300
-20g-20m=-340
solve the equation, then divide -5 to both sides to isolate the m
-5m=-40
m=8
substitute the value of m into one equation to find the other value
g+8=17
g=9
write them in ordered paired form
(9, 8)

Answer:
price of a computer that she could afford R 9230.769
Step-by-step explanation:
Given data
amount pay = R500 per month = 500 × 24 = R 12000 total pay
time period =24 months = 24 /12 = 2 years
rate = 15 % per annum
to find out
price of a computer that she could afford
Solution
we know formula
Amount Paid = Principal × (1+(RT/100))
put value principal pay and R and T and we get
principal = Amount / (1+(RT/100))
principal = 1200 / (1+(15 ×2 )/100))
principal = 9230.769
price of a computer that she could afford R 9230.769
