Answer:
D = sqrt[ (2-4)^2 + (7- (-1))^2] = ~8.2
Step-by-step explanation:
D = sqrt[ (Fx-Gx)^2 + (Fy- Gy)^2]
Let's call the store value as s and the wholesale price as w. A store prices tapes by raising the wholesale price 50%(0.5 in decimals) and adding 25 cents, writing this as an equation, we have

If we invert the equation we're going to find the the wholesale price as a function of the store price.

Now, to find the wholesale price if the sales price is $1.99, we just need to evaluate s = 1.99 on the function we created.

The wholesale price is $1.16.
B. -7
The answer all comes down to you getting -7/f.
