Jackson is buying school supplies for his third grade class, which has 30 students. Each student needs 5 pens, 3 notebooks, 1 binder and 2 highlighters. Pens cost $0.50, notebooks cost $1.25, binders cost $4.25, and highlighters cost $0.75. If Jackson gets a $100 teacher discount, how much does he spend on school supplies? Let's answer step by step:
First calculate the cost of the pens for one student by multiplying the number of pens by the cost per pen: 5 pens * $0.50 / pen = $2.50. Then calculate the cost of the notebooks for one student by multiplying the number of notebooks by the cost per notebook: 3 notebooks * $1.25 / notebook = $3.75. Then calculate the cost of the highlighters for one student by multiplying the number of highlighters by the cost per highlighters: 2 highlighters * $0.75 / highlighter = $1.50. Now add the cost of all the different supplies to find the total cost for one student: $2.50 + $3.75 + $1.50 + $4.25 = $12.00. Now multiply the cost per student by the number of students to find the total cost before the discount: 30 students * $12.00 / student = $360.00. Now subtract the teacher discount to find the final cost: $360.00 - $100.00 = $260.00. The answer: 260.
