Answer:
$14.40
Step-by-step explanation:
She spent 12 dollars and has 1/5 left.
This means $12 is 4/5 of her original money.
$12=4/5 of the original money
$12+ $[12•(4/5)]=4/5+ (1/5)
$12+$[2.4]=5/5
$14.4=5/5 of the original money
She originally had $14.40
The bike is now $500. The price goes down by 20% each year.
500(0.20) = 100
The bike decreases by $100 each year.
After 5 years at $100 less per year, the bike will be $0.00.
You use rise over run
so say a graph is going up 2 for every 1 going across
the slope would be 2 over 1
