Question

pc solution sells regular keyboards for $84 and wireless keyboards for $105. Last week the store sold three times as many regular keyboards as wireless.If total keyboards sales were $4,998,how many of each type were sold?

Answer 1

Well since regular ones (r) are 84 each...and wireless (w) are 105 each...and the total is 4998 we have

84r + 105w = 4998

We also know that 3 times the sales of wireless sales were the regular sales...so

r = 3w

So after substitution we have

84(3w) + 105w = 4998

Can you take it from here?
