Answer:

Gilda can send 125 messages in one month.

Explanation:

Given,

Total bill of 1 month = $50

Fixed charge of 1 month = $40

Charge of 1 message = 8 cents

∵100 cents = $1

∴8 cents = $0.08

Therefore Charge of 1 message = $0.08

We have to find out the number of messages that Gilda can send in 1 month.

Solution,

Let the total number of messages that Gilda can send in 1 month be 'x'.

Total bill of the month is the sum of fixed charge and charge of 1 message multiplied with total number of messages.

So, framing the above sentence in equation form, we get;

Total bill of 1 month =Fixed charge of 1 month+Charge of 1 message× total number of messages

On substituting the given values, we get;


40+0.08x=50\\\\0.08x=50-40\\\\0.08x=10\\\\x=(10)/(0.08)=125

Hence Gilda can send 125 messages in one month.
