Question

Nathan has a collection of 220 baseball cards. He lets his brother 1/4 of his collection and sells 20% of his collection to the baseball card shop. He takes 15 cards to school to give to his friends. How many baseball cards remain in Nathan’s collection?

Answer 1

The baseball cards remain in Nathan’s collection is 106 cards

Step-by-step explanation:

Total number of cards Nathan has= 220

Number of cards he let his brother have = 1/4 of his collection

=
`(1)/(4) * 220` = 55 cards

Number of cards he sells = 20% of his collection

=
`(20)/(100) * 220`

=44 cards

No of cards he gives to his friends=15 cards

Remaining cards = total number of cards – (no of cards he gave to his brother+ cards he sold+ cards he gave to this friends)

= 220 – ( 55+44+15)

=220-114

=106 cards

baseball cards remain in Nathan’s collection is 106 cards
