Having spent $20.16 on ingredients, Jessica and Jonathan want to know how much they should charge for lemonade. Remember, they made enough for 15 servings. What is the minimum amount that they should charge for a serving of lemonade in order to make a profit of $20.00 (meaning that they make back all the money they spent plus $20.00 extra)? Round your answer to the nearest hundredth.

Step-by-step explanation:

The amount spent on the ingredients  = $20.16

The number of servings prepared  = 15

The profit to b made in total  =  $20.00

Let us assume the minimum selling amount of per serve of lemonade = $ m

So, the selling amount of 15 per serving  = 15 x ( cost of each serving)  

=  15 x ( $ m)  = 15 m

Now, Profit  = Total Selling price  - Total Cost price

⇒ $20  =  15 m - $20.16

or, 40.16  = 15 m

or, m =  

⇒ m = 2.6773333

Now, rounding off to nearest hundredth, as 7 > 5 so 2,677333 ≈ 2.68

Hence, they should charge $2.68 per lemonade serving in order to earn $20 profit in total.

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
