Question

Lucy had decided to start a dog sitting business. She needed 45 in supplies to get her new venture started. She charges2 for each dog she walks in 20 minutes. If Lucy has walked 42 dogs so far, how much money has she made?

Answer 1

After walking 42 dogs and charging $2 per dog, Lucy's total revenue was $84. Subtracting her initial supply cost of $45, Lucy's profit is $39.

Step-by-step explanation:

Lucy is starting a dog walking business and needs to calculate her earnings so far. She spent $45 on supplies and charges $2 for each dog she walks for 20 minutes. To calculate Lucy's earnings, we need to multiply the number of dogs she walked, which is 42, by the amount she charges per dog, which is $2.

So the calculation would be 42 dogs x $2 per dog = $84. However, since Lucy had an initial expense of $45, we need to subtract this amount from her total revenue to get her net earnings.

The net earnings are therefore calculated as $84 (total revenue) - $45 (initial supplies cost) = $39. Lucy has made a profit of $39 after walking 42 dogs.
