Answer:
D
Step-by-step explanation:
Add all the units together 8+11+6+8=45
then divide by the the number of units there are which is 5 so 45÷5 =9
The cost of the shirts is stable, so we can subtract $1150 - $84, which = $1066. Now we want to find how many watches we can buy with $1066, or how many times $99 fits into $1066. So divide 1066 by 99 to get 10.77. You can't buy 77ths of a watch, so round it down to 10 and you have your answer. Samantha can buy 10 watches.
X^2 = 30
x = +5.48 and x = -5.48
