Step-by-step explanation:
You can use the unituary method in this one
First card:
$25/750 min
divide both sides by 750 to figure out how many $ per min the calling card would be
25/750=0.033333333333333333333333333333333333333
750/750=1
the first card costs $0.03333333(going on)/min
Second card
$40/1,300 min
Divide both sides by 1,300
40/1300=0.03076923
1300/1300=1
Second card costs $0.03076923/min
$0.03076923<$0.03333333(going on)
therefore the second card is the better deal

Answer:
192
Step-by-step explanation:
so you basically make an equation like this:
4*4(5+7)
4*4(12)
4*48
=192
187.69 because 3003.04 divided by 16 is 187.69
<span>Total numbers of whole number that has a sum of 12.
Let’s start counting
1. 11 + 1 = 12
2. 10 + 2 = 12
3. 9 + 3 = 12
4. 8 + 4 = 12
5. 7 + 5 = 12
6. 6 + 6 = 12
7. 12 + 0= 12
Therefore, there are 7 pairs of whole numbers being added that have a sum of 12.
