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?
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 = $<<5*0.5=2.50>>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*1.25=3.75>>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 = $<<2*0.75=1.50>>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 = $<<2.5+3.75+1.5+4.25=12.00>>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 = $<<30*12=360.00>>360.00
Now subtract the teacher discount to find the final cost: $360.00 - $100.00 = $<<360-100=260.00>>260.00
