Answer:
16 attires
Step-by-step 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
