Answer:
Bobby made 16 color copies for his book report.
Step-by-step explanation:
Given:
Total money spent to make copies = $4.03
Cost of black-and-white copies in all = $2.75
Cost of each color copies = 8 cent
now we know that
1 cent = $0.01
8 cent = $0.08
We need to find the number of color copies made.
Solution:
Let the number of color copies made be 'x'.
No we can say that;
Total money spent to make copies is equal to sum of Cost of black-and-white copies in all and Cost of each color copies multiplied by the number of color copies made.
framing in equation form we get;
[tex]2.75+0.3x=4.03[/tex]
Subtracting both side by 2.75 we get;
[tex]2.75+0.08x-2.75=4.03-2.75\\\\0.08x = 1.28[/tex]
Now dividing both side by 0.08 we get;
[tex]\frac{0.08x}{0.08}=\frac{1.28}{0.08}\\\\x=16[/tex]
Hence Bobby made 16 color copies for his book report.
