Answer:
Step-by-step explanation:
(x)7 steak(dependent variable) = $44.10
(y)11 steak(independant variable)=$69.30
y=kx
11/7=1.57142857143
reduce that to 3 decimal spaces
y=1.57x
y=1.57(7)
11=1.57(7)
or
cross multiply ![\frac{7}{44.10} \neq \frac{11}{69.30}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B44.10%7D%20%5Cneq%20%5Cfrac%7B11%7D%7B69.30%7D)
7 × $69.30 and 11 × $44.10
and get 485.1 for both
That problem has only one solution
