Hi there! The answer is 5.
As you mentioned in the question, the amount of chores Janie does is represented by c.
When we know this we can set up an expression which represents the total amount of money Janie earns.
She always receives $3.
She also receives
$2 × the amount of chores
$2 × c = 2c
The expression which represents Janie's total earnings is 3 + 2c.
Now we can start solving.
Subtract 3 from both sides.
Divide both sides by 2.
Hence, Janie must do 5 chores to earn enough money to buy a CD.
Answer:
b. 20 m
Step-by-step explanation:
Let A represent the area
Let d represent the diagonal
then
Then
d² = 2A
then
Based on the fact that one shelter received twice as much as the other, the amount received by each shelter are $2,000 and $4,000.
<h3>What amount did each shelter receive?</h3>
Assuming that the money raised was $6,000, we can assume that the shelter that received less money received x.
The formula for what they received would be:
2x + x = 6,000
Solving gives:
2x + x = 6,000
3x = 6,000
x = 6,000 / 3
x = $2,000
The amount the other shelter received was:
= 2,000 x 2
= $4,000
