Answer:
8x = 32
x = 4
y = 6
Step-by-step explanation:
2.5y + 3x = 27
5x – 2.5y = 5
_____________
8x = 32 (equation obtained after adding the two equations)
x = 32/8
x = 4
Plug x = 4 in 2.5y + 3x = 27
2.5y + 3*4 = 27
2.5y + 12 = 27
2.5y = 27 - 12
2.y5= 15
y = 15/2.5
y = 6
In order to have 4 kg, he must have 20/5 kg. Each bag is 2/5 kg, so 2/5 times 10 is 20/5 or 4kg. Therefore, he bought 10 bags of tangerines for the school party.
The total balance of the amount of money deposited into the account at the end of 4 years is $3194.76.
<h3>What is the total balance?</h3>
Simple interest rate is the interest that is paid only on the principal portion of the amount deposited. Compound interest is when interest is earned on the amount deposited and the interest accrued.
Compound value = amount deposited x (1 + interest rate) ^number of years
800(1.0125)^4 = $840.76
Future value of the account with simple interest = amount deposited + (principal x time x interest rate)
2200 + (2200 x 0.0175 x4) = $2354
Total value = 2354 + 840.76 = $3194.76
