Question

select the correct answer.
blake has b baseball cards. his aunt gave him more cards, increasing his total number of cards by 25%. which expression represents blake’s total number of cards now?
a. ( b + 0.25 )
b. ( b - 0.75b )
c. ( 1.25b )
d. ( 0.75b )

Explanation:

Step1: Understand the percentage increase

A 25% increase means we add 25% of \( b \) to \( b \). Mathematically, 25% is \( 0.25 \), so 25% of \( b \) is \( 0.25b \).

Step2: Calculate the new total

The new total number of cards is the original number \( b \) plus the increase \( 0.25b \). So, \( b + 0.25b \). Combining like terms, we factor out \( b \): \( b(1 + 0.25) = 1.25b \).

Answer:

C. \( 1.25b \)
