Question

a trolley charges $3.00 just to get in the car and $1.00 for each mile traveled. how much would it cost to travel 5 miles? 8 miles? 20 miles?
solve on paper and record your answers in the table.
number of miles (m) | cost in dollars (c)
5 | $square$
8 | $square$
20 | $square$

Explanation:

Step1: Define cost formula

$c = 3 + 1 \times m$

Step2: Calculate cost for 5 miles

$c = 3 + 1 \times 5 = 8$

Step3: Calculate cost for 8 miles

$c = 3 + 1 \times 8 = 11$

Step4: Calculate cost for 20 miles

$c = 3 + 1 \times 20 = 23$

Answer:

Number of miles (m)	Cost in dollars (c)
8	$\$11$
20	$\$23$
