Answer 1

If Sarah's daily income is represented by the variable y and the amount her customers spend is represented by the variable x, then the answer is 
y = 0.15x + 50 

Answer 2

she makes 50 per day so that would be the constant number

 o you have y = 50 + something

her tips are 15% , which is 0.15x

so her pay would be y = 0.15x +50
