The sale price of shrimp at a local grocery store is $1.15 for the first ounce and $0.95 for each additional ounce. Which function rule shows how the cost of shrimp, y, depends on the number of ounces, x?
A - y = 1.15x + 0.95
B - y = (0.95 + 1.15)x
C - y = 0.95x + 1.15
D - y = 0.95(x - 1) + 1.15

Respuesta :

C. y=0.95x+1.15... because 1.15 is the initial cost and 0.95 multiplied by x means x is the number of ounces you purchase after the first.
so say you purchase 5 more ounces then your equation would be 
y=(0.95*5)+1.15
but in this case THE ANSWER IS C!
