Answer:
$75
Step-by-step explanation:
Answer:
$28.83
Step-by-step explanation:
We will use: and then use cross multiplication.
Let's solve the first sale
We have:
percent = 25%
whole = $200
we want to solve for "part". Lets set the equation up before we plug anything in
now plug everything in:
part = $50
what does this mean?
Well it actually means $50 is the amount of money we take away from our original price of $200.
So we subtract that from our total.
$200 - $50 = $150
Next we will do the second sale.
percent = 50%
whole = $150
Use the same equation as above:
part = $75
Answer:
2x+7
Step-by-step explanation:
3x +(-x) = 3x - x, so it's 2x
12 + (-5) is the same situation, just being 12 - 5, so it's 7.
putting them together leaves you with 2x+7
