Wendy had some beads at first. She gave 19 of her beads to her cousin and 16 of her beads to her neighbour. After that, her mother gave her another 19 beads. She had 84 beads in the end. How many beads did Wendy have at first?
Fraction of beads left after giving to her cousin and her neighbour
= 1 -
19 -
16 = 1 -
218 -
318 = 1 -
518 =
1318 Number of beads left after giving to her cousin and her neighbour = 13 u
Number of beads left after her mother gave her another 19 beads = 13 u + 19
13 u + 19 = 84
13 u = 84 - 19
13 u = 65
1 u = 65 ÷ 13 = 5
Number of beads that Wendy had at first
= 18 u
= 18 x 5
= 90
Answer(s): 90
