Question

In a certain country, customers are charged a flat fee of $55.50 for up to 50 local calls. customers pay $0.35 per call for each call above this limit. A customer made 88 local calls what is the bill?

Answer 1

Given that for 50 local calls, customers are charged a flat fee of $55.50.

We were also told that customers pay $0.35 per call for each call above this limit.

Therefore, for a customer with 88 local calls, the bill will be

`\text{ \$55.50+\$0.35}*(88-50)`

Hence,

`\text{\$55.50+\$0.35}*38=\text{ \$(55.50+13.3)}=\text{ \$(68.80)=\$68.80}`

Therefore, the bill of the customer with 88 local calls will be $68.80.
