Answer:
24
Step-by-step explanation:
Given
[tex]Total = 200[/tex]
From the attachment, we have:
[tex]Black = 35\%[/tex]
[tex]Blue = 23\%[/tex]
Required
How many more of black than blue were sold
First, calculate the difference in percentage sold
[tex]d = 35\% - 23\%[/tex]
[tex]d = 12\%[/tex]
Multiply by the total phones sold;
[tex]d * 200 = 12\% * 200[/tex]
[tex]d * 200 = 24[/tex]
Hence, 24 more blacks were sold than blue
