I HAVE 30 MINUTES PLEASE T-T (I'll give 50 points) 1. Sally has a jewelry business. To make a certain necklace, she spends $2.51 on materials and $4.38 on labor. She then sells the necklace for $17.99. Lucy’s profit on the necklace is equal to the sale price minus the cost of materials and labor. (a) How much profit does Sally earn when she sells a necklace? $11.10 (b) What fraction of the sale price of the necklace is profit? (c) What decimal of every dollar of the sale price of the necklace is profit? Round your answer to the nearest hundredth. (d) Sally collected $269.85 selling necklaces at a craft fair. How many necklaces did Lucy sell? (e) How much profit did she earn?

a. $11.10

b. 1 689/1110

c. 1.62

d. 15 necklaces

e. $166.50

Step-by-step explanation:

Materials = $2.51

Labor = $4.38

Cost of production = $2.51 + $4.38

= $6.89

Sales price = $17.99

a. Profits = sales price - cost of production

= $17.99 - $6.89

= $11.10

Sally earn $11.10 when she sells a necklace

b. Sales price = $17.99

Profits = 11.10

Fraction of sale price that is profits = $17.99 / $11.10

Multiply both numerator and denominator by 100

= 1799/1110

= 1 689/1110

c. Sales price = $17.99

Profits = 11.10

Decimal of every dollar of the sale price of the necklace that is profit = $17.99 / $11.10

= 1.6207

Approximately 1.62

d. Total selling price of necklace = $269.85

Selling price of each necklace = $17.99

Number of necklace sold = Total selling price of necklace / Selling price of each necklace

= $269.85 / $17.99

= 15 necklaces

(e)

Profits earned per necklace = $11.10

Total profits earned = Profits earned per necklace × Number of necklace sold

= $11.10 × 15

= $166.50
