You know that 3 times 2 is 6 so 30'times 20 equals 60
<span>So what you would do is you would dived the subscriptions by the cost
Soo...
$40.50/18 =2.25
$33.60/12=2.80
so therefore 12 issue subscriptions for $33.60 would be more

There are 8 proper fractions with a denominator of 30 that are irreducible:
1/30, 7/30, 11/30, 13/30, 17/30, 19/30, 23/30, 29/30
We cannot count any even numerators, as 30 is even and would therefore make the fraction reducible.
We cannot count any numerators that are a multiple of 3, as it is a factor of 30. Likewise we cannot count any numerators that are a multiple of 5.
Answer:
5 hours, y= how much money it will cost, and x represents how many hours
Step-by-step explanation:
y= 15x+45
120= 15x+45
-45 -45
75= 15x
75/15×= 5 hours
