Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is $ 4200
<h3><u>Solution:</u></h3>Given that Cara earns a base pay of $1,800 per month at a car dealership plus a commission of 6% of her sales
Let us first calculate commission earned from selling $40,000 worth of merchandise
commission earned from selling $40,000 = 6 % of $ 40,000
Also given that Cara earns a base pay of $ 1800 per month
So Cara’s total earnings in a month in which she sells $40,000 worth of merchandise is calculated by adding commission earned $ 2400 to base pay $ 1800 per month
<em>Cara’s total earnings in a month = base pay + commission earned</em>
Cara’s total earnings in a month = $ 1800 + $ 2400 = $ 4200
Thus the total earning of Cara in that month is $ 4200
Answer: The length of the ladder is 20 feet.
Step-by-step explanation:
Given : A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 8 feet less than the length of the ladder.
Mathematically,
Let x be the length of the ladder then
Distance from ground to the top of the ladder = x- 8
If distance from the bottom of the ladder to the building is 16 feet.
Since ground makes right angle with building , so the triangle made by ladder should be a right triangle.
By Pythagoras theorem of right triangle , we hae
Hence, the length of the ladder is 20 feet.
