Molly bought 12.5 yards of fabric for $4.50 a yard to make dog beds. she uses 2.5 yards of fabric for each dog bed. she sells each dog bed for $17.50. after subtracting the cost of the fabric, how much money does molly earn if she sells all of the dog beds?

12.5 yds at 4.50 per yd : 12.5 * 4.50 = 56.25what she paid for the fabric

she uses 2.5 yds of fabric for each dog bed12.5 / 2.5 = 5...so she can make 5 dog beds

each dog bed sells for 17.505 * 17.50 = 87.50

87.50 (what she earned from selling the dog beds) - 56.25 (the cost of the fabric) = 31.25so her total profit is $ 31.25 <==

Molly earns $65

Work:

How many dog beds can she make? 12.5 / 2.5 = 5

How much money does she earn from all 5 dog beds? 5 x 17.5 = 87.5

How much does it cost to make all 5 beds? 5 x 4.5 = 22.5

Finally, How much money did she make? She earned $65

Hope this helps!

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
