4
Step-by-step explanation:
100 divided by 25 equals 4.
0.25c - that’s 25% off the cost (c) of the dress
Make it into a simultaneous equation:
5p + 4e = 7.65
4p + 5e = 7.20
Use adding/subtracting formula
The cost of an eraser is $1.44
The equation is y = x - 3. just subtract 3 to get all of the blank spots.
