Answer:
B
Step-by-step explication:
(1/4)/(3/8)=(2/3)
Usually, the more often it's compounded, the better. That's assuming that the percent is equal through all comparisons, however.
Let the regular price be X
x\98.60 x 100=29%
100x\98.60=29(multiply both sides by 98.60 to remove the denominator
100x=2859.4(divide both sides by 100
x=28.594
regular price=$28.594
No the product will be less than 9/10.
This can be easily seen if the fractions are converted into decimals.
The decimal form of the product of 7/8 and 9/10 is 0.867 while the decimal form of 9/10 is 0.9. Therefore, the product of 7/8 and 9/10 is not greater than 9/10
The z-score is 3, because 294-210=84; 84/28=3
