Answer is 13 i hope this helps like it
Let x = original price
Knowing that multiplying the original price and the discount is the discount price. We formulate:
x(1 - 0.40) = 179.94
x(0.60) = 179.94
x = 179.94/0.60
x = 299.9
That is about 300 of the original price.
Solving equations is a basic skill that you must master to deal with a
lot of problems in mathematics, physics, chemistry, administration,
economy, and almost every activity where you need to use a formula or a
model. to solve for h, you follow these steps: 1) multiply both sides by
2 => 2A = (a+b)h; 2) divide both sides by (b+a) => 2A/ (a+b) = h.
So the answer is: h = 2A / (a+b).
