Kate spent $64 on some stationery. 4/11 of the items that she bought

were erasers and the rest were pens. Each eraser cost $1.20 and

each pen cost $1.60. How many erasers and pens did Kate buy

altogether?

Let the total items bought be x.

Erasers = 4x/11, Pens = 7x/11

Erasers = $1.20, Pen = $1.60

4x/11 * 1.2 + 7x/11 * 1.6 = 64

4.8x + 11.2x = 64 * 11

16x = 64 * 11

x = 4 * 11 => x = 44

No. of erasers = (4 * 44)/11, No. of pens = (7 * 44)/11

= 16 = 28
