Respuesta :
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
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 isÂ
y = 0.15x + 50Â
y = 0.15x + 50Â
