# The same phone company offers another plan where they charge $15 per month and$0.25 for each call made or received. Write and evaluate an expression to find the cost for 40 calls during one month. Then make a table showing the cost for 40, 50, 60 and 70 calls.

15+0.25(40)=25 dollars total

0.25(40)=10 dollars just for the 40 phone calls

___callsmoney

40             =           10

50            =            12.5

60            =            15

70           =             17.5

Step-by-step explanation:

25 cents times 40 phone calls would be 10 dollars then you have to add the standard 15 dollars per month for the plan to get your total cost per month if you were to make 40 phone calls.
