Sari has 21 pencil erasers.

let x represent the amount of erases Sam has

3x + x = 28

4x = 28

4x/4 = 28/4

x = 7

Sam has 7 erasers and Sari has 3 times more than Sam.

so 7 x 3 =21

Sari has 21 eraser because if Sam has 7 then sari has 3 times as much so 7 times 3 is 21 then 21 +7 because Sam has 7
