Answer:
base = 15 units
Step-by-step explanation:
We are given area of a triangle = 52.5 sq. units
Height is given as 7 and we have to find the base.
Using formula for area of triangle:
Area of triangle =
52.5 * 2 = base × 7
105 = base × 7
base = 15
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.
