Awireless phone plan costs eric $35 for a month of service during which he sent 450 text messages. if he was charged an fixed a fee of $12.50, how much did he pay per text?

5 cents

Step-by-step explanation:

Let m = cost per message

450m + 12.5 = 35    subtract 12.5 from both sides

450m = 35-12.5

450m = 22.5           divide both sides by 450

m = 22.5/450

m = .05

The cost is $.05 per message  ... 5 cents

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
