Question

Sally lends half her collection of formal attire to her sister Annie, sally then buys four more attires. If she had 12 attires now, how many attires did sally have initially

Answer 1

16 attires

Explanation:

Let us represent the number of attires:

Sally has initially = x

Sally lends half her collection of formal attire to her sister Annie

This means, Sally has currently = 1/2x attires

Sally then buys four more attires. If she had 12 attires now.

Hence, this is expressed Mathematically as:

1/2x + 4 = 12

1/2x = 12 - 4

1/2x = 8

x/2 = 8

Cross Multiply

x = 8 × 2

x = 16

Therefore, the amount of attires Sally had initially = 16 attires
