Hello, Tennant17!
The model for direct variation is y=kx where k is a constant.
In this case, y is m and x is t.
So the equation is m=kt
Plug in the values of m and t to find k.
19= k * 2
Solve for k
k= 19/2
k= 9.5
Plug k back into the equation.
m=9.5t
So the answer is:
B. m=9.5t
Hope this helps :)
Answer:
6 pounds of coffee.
Step-by-step explanation:
First, we determine how much money she spent. 80-31.76 = 48.24
Next, we divide the money spent by the price per unit. 48.24/8.04=6
Therefore, she bought 6 pounds of coffee.
