A philanthropist bought a total of $5760 worth of toys, textbooks and clothes to donate to the needy children. The number of clothes bought was 25% more than the number of toys bought but 25% fewer than the number of textbooks bought. The toy cost $12 each and was $3 more expensive than each textbook but 40% cheaper than each piece of clothes. How many toys and textbooks did the philanthropist donate to the needy children?

100% + 25% = 125%
125% =
125100 = 1
14 100% - 25% = 75%
75% =
75100 =
34The number of clothes is the repeated identity. Make the number of clothes the same. LCM of 1 and 3 is 3.
Price of each textbook
= 12 - 3
= $9
100% - 40% = 60%
60% of price of toys = $12
1% of the price of toys =
1260 100% of the price of toys =
1260 x 100 = $20
Price of each piece of clothes = $20

Total amount spent
= 4 u x 9 + 12 u x 12 + 3 u x 20
= 36 u + 144 u + 60 u
= 240 u
240 u = 5760
1 u = 5760 ÷ 240 = 24
Number of toys and textbooks
= 25 u + 4 u
= 29 u
= 29 x 24
= 696
Answer(s): 696
