The equation y = 4.75x + 20 gives the cost y of towing a car if the car is towed x miles. which statement is true?
for every mile the car is towed, the cost decreases by $20.

for every mile the car is towed, the cost decreases by $4.75.

for every mile the car is towed, the cost increases by $4.75.

for every mile the car is towed, the cost increases by $20.

For every mile the car is towed, the cost increases by $4.75.

Step-by-step explanation:

The given equation is :

Here y is the cost of towing a car if the car is towed x miles.

Lets check each statement:

1. For every mile the car is towed, the cost decreases by $20.

This is false as the cost will increase with each mile and 20 is constant here.

2. For every mile the car is towed, the cost decreases by $4.75.

This is false as the cost will always increase. Cost is directly proportional to miles driven. As miles increases, the cost also increases.

3. For every mile the car is towed, the cost increases by $4.75.

This is true. Here, 20 is constant and 4.75x varies whenever multiplied by a value of 'x'.

Lets check for 2 miles :

= $29.5

Lets check for 3 miles :

= $34.25

Difference of dollars

So, this is the true statement.

4. For every mile the car is towed, the cost increases by $20.

This is false as 20 is a constant number in the given equation.

$35.59 in pounds
