Its D i just took the test
My initial answer was $2750.45, and I will show you my calculations. Calc : 6774.5 ÷ 100 = 67.745 67.745 × 2.7 = 182.9115 182.9115 × 22 = 4024.053 6774.5 - 4024.053 = 2750.45 = $2750.45 At first I thought this was correct, but after studying my answer I realise that the amount of interest would rise as the amount of money went up, therefore my calculations are very wrong. If I work out the answer, I will get back to you, but the calculation is more complicated than I first predicted

Answer:
yes it is.
x = 4 and y = -3
Step-by-step explanation:
Solve simultaneously using elimination method:
equation 1 - equation 2
3x + y = 9 equation 1
-2x + y = 5 equation 2
_________
x = 4
plug 4 into any of the 2 equations and solve for y.
3(4) + y = 9
12 + y = 9
12-12 + y = 9-12
y = -3
