Answer:
Gilda can send 125 messages in one month.
Step-by-step 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=\frac{10}{0.08}=125](https://tex.z-dn.net/?f=40%2B0.08x%3D50%5C%5C%5C%5C0.08x%3D50-40%5C%5C%5C%5C0.08x%3D10%5C%5C%5C%5Cx%3D%5Cfrac%7B10%7D%7B0.08%7D%3D125)
Hence Gilda can send 125 messages in one month.
