Answer: The required number of miles rode is 4.6875.
Step-by-step explanation: We are given to solve the following situation for the value of d :
Tori needed to take a taxi. The fare for riding in a taxi is a $3 fixed charge and $0.80 per mile. The fare for a ride of d miles is $6.75.
According to the given information, we have
![3+0.80d=6.75\\\\\Rightarrow 0.80d=6.75-3\\\\\Rightarrow 0.80d=3.75\\\\\Rightarrow d=(3.75)/(0.80)\\\\\Rightarrow d=4.6875.](https://img.qammunity.org/2021/formulas/mathematics/college/y8eieaxftf1hbriti81jmlduooqzsrlf30.png)
