Ajewelry maker produces necklaces that sell for $85 each. the jewelry maker cost include $35 in materials for each necklace plus fixed cost of $1650, how many necklaces must the jeweler fix to break even?

220

Step-by-step explanation:

Let us assume that x number of necklaces are to be fixed to break even i.e. cost price = profit.

Now, cost for x necklaces is 35x + 1650, and selling price is 85x. {As per given condition}

Therefore, profit will be = 85x - (35x +1650) =50x -1650

Hence, to make break even, the condition is

50x - 1650 = 35x + 1650

⇒15 x =3300

⇒ x =220.

Hence, 220 number of necklaces must the jeweler fix to break even. (Answer)  

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
