Answer:
Step-by-step explanation:
Here is the complete question
Lakeisha spent $4.57 on color and black-and-white copies for her project. She made 7 more black-and-white copies than color copies. How much color did she make?
Key: color- $0.44 per page
black-and-white: 7 cents per page
Let the amount of color be x
Let the amount of black and white be y
If amount per page of color is $0.44, then x color will cost 0.44x
If amount per page of white and black cost $0.07, then y white and black will cost $0.07y
Since She made 7 more black-and-white copies than color copies, this means:
y = x+7.... 1
If the total spent on black and white is $4.57 then;
0.44x+0.07y = 4.57.... 2
Substitute 1 into 2
0.44x+0.07(x+7) = 4.57
0.44x + 0.07x+0.49 = 4.57
0.51x = 4.57-0.49
0.51x = 4.08
x = 4.08/0.51
x = 8
This means that I made 8 color copies
