The awnser is ______ ____ ___ _____ __
Answer:
$104
Step-by-step explanation:
1. Set up your problem as a ratio. Put the percentage over 100 on one side of the equation and the the cost of the online prescription over the in-store prescription on the other side. Since we don't know the cost of the in-store prescription, we can write this as x.
78/<em>x</em> = 75/100
2. Next, cross multiply.
75<em>x</em> = 7800
3. Divide by 75 on both sides.
<em>x</em> = 104
4. To check your work, multiply 104 by .75 (the decimal equivalent of 75%) to make sure you get back to the original $78.
104 x .75 = 78
Now you know that your answer is correct.
Hope this helps!
