Fantom [35]

Answer:

The better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Step-by-step explanation:

To find which is the better deal, you have to determine which one offers a lower unit price by dividing the price of each package by the number of balls in the pack:

$4.47/12=$0.37

$14.46/18=$0.80

According to this, the answer is that the better deal is the 12 pack because the unit price is $0.37 which is lower than the unit price of the 18 pack that is $0.80.

Solution:

Let the price of each apple = $ x

Let the price of each orange = $ y

Martha bought 3 apples and 6 oranges

She had $10 in her wallet which was enough money for the purchase

Thus the equation is:

Total amount = 3 apples(price of each apple) + 6 oranges(price of each orange)

Ahat [919]

Answer: c. $\dfrac{90}{1800}\times100\%$

Step-by-step explanation:

As per given , we have

Total number of residents injured from roller-skating =1,800

Total number of deaths from roller-skating = 90

Formula for Mortality rate : $Mortaility\ rate= \dfrac{Deaths\ due \ to\ injury}{Tota\ injuries}$

Then, the proportional mortality ratio (%) due to roller-skating was

= $\dfrac{90}{1800}\times100\%$

= 5%

Hence, the correct answer is c. $\dfrac{90}{1800}\times100\%$
