8) The table below shows the cost of office supplies. Item Box of staples Box of pens Ream of paper Cost $1.25 $2.91 $5.27 For each hour the office staff works, you earn $22.44. Use a formula to express the net income 1, in dollars, that is the result H hours of work by the office staff minus the cost of purchasing S boxes of staples, P boxes of pens, and R reams of paper. a) I = 22.44H - 1.255 - 2.91P - 5.27R b) I = 1.25H + 2.915 + 5.27P + 22.44R c) I = 1.25H + 2.915 + 5.27P - 22.44R d) I = 22.44H - 1.25P - 2.915 - 5.27R
