Answer:
Step-by-step explanation:
Let x be the no. of minutes
Plan A
Monthly rental = $12
Call charges for 1 minute = 7¢
1 cents = 0.01 dollars
So, Call charges for 1 minute = $0.07
Call charges for x minutes = 0.07 x
Total cost of Plan A = 12+0.07x
Plan B
Monthly rental = $15
Call charges for 1 minute = 5¢
1 cents = 0.01 dollars
So, Call charges for 1 minute = $0.05
Call charges for x minutes = 0.05 x
Total cost of Plan B = 15+0.05x
An inequality in terms of the number of minutes which shows when Plan A is less expensive than Plan B=
Solving the inequality :
So, the no. of minutes must be less than 150 for Plan A to be less expensive than Plan B
Hence an inequality in terms of the number of minutes which shows when Plan A is less expensive than Plan B is
