You're really good at investing and you have $1,500 in your investment account. you make 8.5% interest a year on your investment account! for a year you owe $1,600 on a credit card. you pay 19% interest a year on this credit card debt. answer these questions: some of the answers are incorrect. try is a hint: how much are you making on your investment? calculate: $1,500 * 8.5%. what do you pay in interest on your card? you do the math: $1,600 * 19%. looks like a huge loss of money, right? enter the loss as a negative value. how much money are you making on your investment in a year? $ how much money are you paying in interest in a year on your card? $ what's your total gain/loss that year? $ enter a negative value for a loss.

Step-by-step explanation:

To determine how much are you making on your investment, we will apply the simple interest formula. It is expressed as

I = PRT/100

Where

P = principal or amount invested,

R = interest rate

T = time

From the information given,

P = $1,500

T = 1 year

R = 8.5

I =( 1500×8.5×1)/100

I = $127.5

For a year you owe $1,600 on a credit card. You pay 19% interest a year on this credit card debt.

Interest paid = (1600×19×1)/100 = $304

The loss is 304 - 127.5 = - $176.5

x/7.50 = 15

x= 7.50 / 15 divide

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
