Answer:
<u>The taxi ride was for 23 miles.</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Function of total cost (C)ₙ = 10 + 1.50n
n = Miles of the taxi ride
C = Cost in dollars of the taxi ride
Total cost = $ 44.50
2. For how many miles was the taxi ride?
Let's replace the cost of the taxi ride in the function given for solving for n, this way:
10 + 1.50n = 44.50
1.50n = 44.50 -10
1.50n = 34.50
n = 34.50/1.50
n = 23
<u>The taxi ride was for 23 miles.</u>
Answer:
The answer is x = 3
Step-by-step explanation:
