Sales Tax would be considered a) percent increase, because it is an added amount onto the total.
Discount would be considered b) percent decrease, because it takes a certain amount off of your total.
Tip would be considered a) percent increase, because similar to sales tax, you must add it on to your total.
You're equation will look like:
R = 1167 + 1167 + 1167 - 239
To get the answer, simplify
R = 1167 + 1167 + 1167 - 239 = 3262

we know the triangle is an isosceles, so it has twin sides, and then the hypotenuse, since it's a right-triangle, we can just use the pythagorean theorem for that.

Answer:
A) 2.8 m
Step-by-step explanation:
The formula for the volume of a right rectangular prism is:
Volume = Length × breadth × height
We can just put in the values that we know to find the height.
110.1 = 7.8 × 5.1 × height
height = 110.1 ÷ 7.8 ÷ 5.1
height ≈ 2.8 (rounded to nearest tenth)
Thus, the answer is Option A.
