To find the original price, you could use a variable to represent the original price in this equation;
Let p represent the original price
.70 × p=11.20
to solve this, we'd isolate the variable (p)
p=11.20 ÷.70
p=16
The original price was $16

Answer:
Equations:
<u>Mia: 10 + 10x = y</u>
<u>Julie: 100 - 5x = y</u>
Solved: <u>(6, 70)</u>
Step-by-step explanation:
Mia: 10 + 10x = y
She already has 10 (<u>10</u>) and gains 10 (<u>+10</u>) per day (<u>x</u>). Total is y gained.
Julie: 100 - 5x = y
She already has 100 (<u>100</u>) and loses 5 (<u>-5</u>) per day (<u>x</u>). Total is y gained.
Then I simply solve
10 + 10x = y
100 - 5x = y
Resulting in (6, 70)
F(-2) when F(x)=5^x is 1/25
ANSWER:
B. $3.50
STEP BY STEP EXPLANATION:
We start out with buying the stock for $15.75 then sell it at $19.25. We need to find the difference.
Subtract $15.75 from $19.25
19.25 - 15.75 = 3.50
To check your work add $3.50 to $15.75
15.75 + 3.50 = 19.25
