25 of his money to buy 3 identical staplers. He spent the rest of his money to buy another 4 such staplers and 3 identical notebooks.
- What fraction of Asher's money was spent to buy the 3 notebooks? Give your answer in the simplest form.
- For every 3 notebooks bought, 1 additional notebook was given free. How many notebooks would Asher get in total if he were to spend all his money to buy notebooks only?
(a)
Cost of 3 staplers =
25 of his money
Cost of 1 stapler
=
25 ÷ 3
=
25 x
13 =
215 of his money
Fraction of Asher's money spent to buy the 4 staplers and 2 notebooks
= 1 -
25 =
35 Cost of 4 staplers
= 4 x
215 =
815 of his money
Fraction of Asher's money spent to buy the 3 notebooks
=
35 -
815 =
915 -
815 =
115 (b)
115 of Asher's money = 3 notebooks
1515 of Asher's money = 15 x 3 = 45 notebooks
Number of free notebooks
= 45 ÷ 3
= 11 r 1
Total number of notebooks that Asher would get
= 45 + 11
= 56
Answer(s): (a)
115; (b) 56
