Answer:
Check attachment.
Step-by-step explanation:
I graphed it.
The population standard deviation, σ = 1.68, the sample standard deviation, s = 1.95, the sample mean =7.23, and the sample size, n = 39.The test statistics is given by
T=(n - 1) (s / σ)²
= (39 - 1) (1.95 / 1.68)²
= 38 (1.35)= 51.196
Move all the x terms to one side and solve for x. 15x-10x=21-6 : 5x/5=15/5 : x=3
<span>well first off, you take 1350/9=150
then you add it all together 1350+150=1500
then your full answer would be $15 was the original price
