3 0

Answer:

20

Step-by-step explanation:

Patrica got 80% correct.  She missed 4 problems, so that must have been the remaining 20% of the test.

Therefore:

4 = 20% x

Percent means out of 100, so:

4 = (20/100) x

4 = 1/5 x

x = 20

There were 20 problems on the test.

Golf balls come in a variety of packages. A particular brand of golf balls come in packages of 12 or in packages of 18. The 12-p
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.
