Question

Craig likes to collect vinyl records. Last year he had 63 records in his collection. No he has 112 records. What is the percent increase in his collection? Round to the nearest whole.

Answer 1

Collection increased by 78%.

Explanation:

Last year number of vinyl records in Craig's collection = 63

Now he has number of vinyl records = 112

Number of vinyl records increased = 112 - 63 = 49

Percentage increase in his collection =
`\frac{\text{Number of records increase}}{\text{Number of records last year}}* 100`

=
`(49)/(63)* 100`

= 77.8

≈ 78%

Therefore, his collection increased by 78%.
