Jenna is making a costume for her role in Oliver Twist. She needs to make an overskirt and two petticoats. Each skirt uses a rectangle of material that measures 12 feet by 4 feet. She also needs to make a bodice that uses 2 square feet of material for the shirt and 5 square feet of fabric for each of the sleeves. If the material she uses costs $3 per square foot, how much does she spend on the material in total? Let's answer step by step:
First find the amount of material needed for one skirt: 12 feet * 4 feet = 48 square feet. Then multiply that number by the number of skirts to find the total material used on the skirts: 48 square feet / skirt * 3 skirts = 144 square feet. Then find the total amount of material she uses for the sleeves: 5 square feet / sleeve * 2 sleeves = 10 square feet. Then add the amount of material she uses for each part of the dress to find the total amount of material: 10 square feet + 144 square feet + 2 square feet = 156 square feet. Then multiply the total amount of material by the cost per square foot to find the total cost: 156 square feet * $3 / square foot = $468. The answer: 468.
