Suppose the average amount spent per shopper at the Super Fresh Grocery Store last month was $46.10. A sample of 25 transactions from last month was randomly selected. Another random sample of 50 transactions was also collected. We can be certain that the sampling error from the sample of 50 customers will be less than the sampling error from the 25 customers. True False

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

pretty sure 750 each month!
