Ajewelry maker works 6 days a week, makes 15 necklaces per day on average, and charges $18 a necklace. if she lowers her price to $10 a necklace, by how many necklaces per day on average must she increase her production to make the same amount of money per 6-day workweek?

The number of necklaces per day on average must she increase her production is 12 per day.

Given that,

Based on the above information, the calculation is as follows:

For 6 days, the total cost should be

Since the price is decreased by $10

So, the number of necklaces should be

= 162

Now per day it should be

= 27

So, the increase per day should be

= 27 - 15

= 12

Therefore we can conclude that the number of necklaces per day on average must she increase her production is 12 per day.

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'.
