Answer
Find out the what was his total cost .
To prove
As given
A tent was marked up 150% from an original cost of $52.
Last Friday, Ethan bought the tent and paid an additional 10% in sales tax.
Than the equation becomes
150 % is written in the decimal form .
= 1.5
10 % is written in the decimal form .
= 0.1
cost of the tent when 150% marked up from origianl price = 1.5× 52
= $ 78
cost of the tent = origianl cost + 150% marked up from origianl price
= $52 + $78
= $ 130
Sales price on the tent = $130 × 0.1
= 13
Total cost of the tent = $130 + $13
= $143
Therefore the cost of the tent is $143.
Using a system of equations, it is found that she made:
- 141 free throws.
- 168 two-point field goals.
- 53 three-point field goals.
For the system, we have that:
- x is the number of free throws made.
- y is the number of two-point field goals made.
- z is the number of three-point field goals made.
She made 362 shots, hence:
She scored 636 points, hence:
- Observation: I used 636 as there would not be a solution(number of field goals cannot be a fraction) if 634 was used.
She made 27 more 2-point field goals than free throws, hence:
Then:
Equaling both equations for z, finding x:
Then, to find y and z:
She made:
- 141 free throws.
- 168 two-point field goals.
- 53 three-point field goals.
