Final answer:
The mechanic in Texas needs to work for 5 days each month at a rate of $6 per day to make a monthly car payment of $30.
Step-by-step explanation:
To calculate the number of days a mechanic in Texas would need to work in order to pay a monthly car payment of $30 when earning $6 a day, we can use a simple division. The formula we will use is:
Number of days to work = Monthly payment / Daily earnings.
By plugging in the values we get:
Number of days to work = $30 / $6 = 5 days.
Therefore, the mechanic would need to work for 5 days each month to cover the cost of the monthly car payment.
