Answer:
$3600 per year into savings
Step-by-step explanation:
He makes 1500 dollars a month
1/5 of that goes into saving
1/5*1500 = 300
300 per month goes into savings
We want to know how much goes into savings per year
There are 12 months in a year, so we need to multiply by 12
300 per month * 12 months/ year = 3600 per year
$3600 per year into savings
Answer:
$64
Step-by-step explanation:
After using a 25% discount coupon, they paid 48 for the video game.
It means, <em>which number, decreased by 25%, would give us 48?</em>
<em />
First, 25% to decimal is:
25/100 = 0.25
Now, if we let the original price be "x", we can say:
x decreased by 0.25 of x would give us 48
Translating this to algebraic equation gives us:
x - 0.25x = 48
Now, we solve this:

If they paid full price, the video game would cost $64
