Elza [17]

The amount he invested in the account that yields 4.5% interest is $7,500.

The amount he invested in the account that yields 2.5% interest is $12,500.

<h3>What is the system of equations that represent the question?</h3>

a + b = $20,000 equation 1

0.045a + 0.025b = $750 equation 2

Where:

a = amount he invested in the account that yields 4.5% interest

b = amount he invested in the account that yields 2.5% interest

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Multiply equation 1 by 0.025

0.025a + 0.025b = 500 equation 3

Subtract equation 3 from 2

250 = 0.02a

a = 12,500

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Subtract 12,500 from 20,000

20,000 - 12,500 = $7,500

An animal shelter houses ferrets, cats, and dogs. There are 108 animals at the shelter. Of the
Korvikt [17]

Number of dogs in the shelter are 12

<u>Step-by-step explanation:</u>

Step 1:

Given that total animals = 108 and number of ferrets = 1/3 of 108. Find number of ferrets in the shelter.

Number of ferrets = 1/3 of 108 = 1/3 × 108 = 36

Step 2:

Given that of the remaining animals, number of cats = 5/6. Find the remaining animals and the number of cats.

Remaining number of animals = 108 - 36 = 72

Number of cats = 5/6 of 72 = 5/6 × 72 = 60

Step 3:

Find number of dogs in the shelter.

Number of dogs = 108 - (36 + 60) = 108 - 96 = 12
