Krystal invested $12,000 in an account that pays 5% annual compound interest. Krystal will not make any additional deposits or withdrawals. How much will be in Krystal's account at the end of the two years?

Step-by-step explanation:

Step one:

given data

principal= $12,000

rate= 5%= 0.05

time = 2years.

Step two;

the compound interest formula is

A= P(1+r)^t

substituting we have

A=12000(1+0.05)^2

A=12000(1.05)^2

A=12000*1.1025

A=13230

Krystal's account at the end of the two years will be $13230

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
