Answer: -600 and 1600 were invested into the two accounts.

Step-by-step explanation:

x = amount invested in the first account.

y = amount invested in the second account.

You start off with this equation

x + y = 1000

0.08x + 0.09y=86

Subtract both sides by y.

x=1000-y

Subsitude 1000 - x for x for the second equation.

0.08(1000-y)+0.09y=$86

Use the distributive property to solve for y.

80-0.08y+0.09y=86

80-0.01y=86

6=-0.01y

=-600

Subsitude -600 for y in the first equation and solve for x.

x-600=1000

x=1600

-600 and 1600 were invested into the two accounts.

Brian, Steve, and Rita invested a total of $24,000 in a business. Each person invested the same amount. Unfortunately, in the fi
stellarik [79]

Answer:

Option C: -$1500 is the correct answer.

Step-by-step explanation:

Given that:

Total amount invested in business = $24,000

Loss suffered in first quarter = $4500

As the amount is shared by Brian, Steve and Rita equally, therefore,

Loss of each person = \frac{Loss}{Number\ of\ people}

Loss of each person = \frac{4500}{3} = \$1500

As loss is defined by decrease in the investment,

Loss of each person = -$1500

Hence,

Option C: -$1500 is the correct answer.
