Answer:
Emma will pay $5.25
Step-by-step explanation:
In order to find this, we first need to find the amount of the discount. We can do that by taking the overall amount and multiplying it by the percentage decrease.
$7.50 * 30% = $2.25
Now since we know the size of the discount, we can subtract it from the original cost.
$7.50 - $2.25 = $5.25
Answer:
Let's solve for x. x=2y
Step-by-step explanation:
Let's solve for x.
x−2y=0
Step 1: Add 2y to both sides.
x−2y+2y=0+2y
x=2y
Let's solve for y.
x−2y=0
Step 1: Add -x to both sides.
x−2y+−x=0+−x
−2y=−x
Step 2: Divide both sides by -2.
−2y/−2=−x/−2
y=1/2x
