Step-by-step explanation:
Answer:
x=-6
y=-11
Step-by-step explanation:
x-y=-5
7x+3y=-75
x=5+y plug that in to the second equation
7(5+y)+3y=-75
35+7y+3y=-75
10y=-75-35
10y=-110
y=-11
plug y into first equation
x+11=5
x=5-11
x=-6
To answer this problem, let p be the price of each scrub. The total bill (t) is the sum of the price of the potting soil (s) and of the 9 scrubs (n). This is depicted in the equation,
$11.50 + 9p = $94.75
The value of p from the equation is 9.25. Thus, each scrub costs $9.25. The answer is letter C.
