You earn $49 for washing 7 cars. How much do you earn for washing 4 cars?

ICE Princess25 [194]

Answer:

Step-by-step explanation:

We can use the rule of three!

We know we have the following relationship:

$\frac{49}{7} = \frac{x}{4}$

From here, we can solve this like any other equation:

$4(\frac{49}{7}) = x\\x = 28$

Therefore, you would earn $28 after washing 4 cars.

Good luck!
