Mixed Operations

Bracelets for the Craft Sale Julie is making friendship bracelets to sell at a craft sale. Each bracelet uses 13 inches of craft thread. Each skein of thread that Julie buys is 7 yards long, and a pack of 5 skeins costs $7.95.

A. How many bracelets can Julie make with five skeins of thread?

B. Julie sells her bracelets for $2.75 each. If she sells ALL of them (total bracelets from Part A), how much will she be paid?

C. Julie would like to make a profit of $300, after her expenses are subtracted. Julie had to pay $25 to participate in the craft fair and she had to buy the thread. To make a profit of $300, how many bracelets will she need to sell?

Mixed Operations

Bracelets for the Craft Sale Julie is making friendship bracelets to sell at a craft sale. Each bracelet uses 13 inches of craft thread. Each skein of thread that Julie buys is 7 yards long, and a pack of 5 skeins costs $7.95.

A. How many bracelets can Julie make with five skeins of thread? 7 yards x 36 inches/yard = 252 inches of thread in one skein 252 ÷ 13 inches = 19.38 bracelets per skein 19 bracelets per skein x 5 skeins = 95 bracelets (Total inches of the 5 skeins combined wouldn’t necessarily be used to calculate number of bracelets, since each skein will have 5 inches left over – the leftover sections would need to be tied together to make another bracelet.) B. Julie sells her bracelets for $2.75. If she sells ALL of them (total bracelets from Part A), how much will she be paid? 95 x 2.75 = $261.25 C. Julie would like to make a profit of $300, after her expenses are subtracted. Julie had to pay $25 to participate in the craft fair and she had to buy the thread. To make a profit of $300, how many bracelets will she need to sell? Expenses: $25 + 2 x 7.95 (she’ll need to buy a second pack of thread to make enough bracelets) = 25 + 15.90 = $40.90 $300 + $40.90 = $340.90 – need to sell $340.90 to make enough to cover expenses and earn $300. $340.90 ÷ 2.75 = 123.96 = 124 bracelets 124 bracelets need to be sold.
