Real-Life Math -- Solution
You need to calculate the cost of laptops vs tablets for the 4,200
junior high students in your district.
Cost of laptops = [$480 -
(480 x 0.25)] x 4,200
Cost of laptops = [480 - 120] x 4,200
Cost
of laptops = 360 x 4,200
Cost of laptops = $1,512,000
Cost
of tablets = [$399 - (399 x 0.15)] x 4,200
Cost of tablets = [399
- 59.85] x 4,200
Cost of tablets =339.15 x 4,200
Cost
of tablets = $1,424,430
Tablets are slightly cheaper,
but both options fit within your budget. You'll have to carefully consider
which devices would be best for your students.
