Su-Lin earns money during the summer by walking dogs. She is walking 2 dogs today and charges $1.50 per hour for each dog. She can walk 3 dogs at a time. Today she is walking dogs for 1 1/2 hours. How much money will she make?
My answer is $3, is this correct?
she charges $1.50 per dog-hour
two dogs today for one and a half hours ... how many dog-hours?
her full dog capacity (3) is spurious information
To calculate the total amount of money Su-Lin will make, we need to find the amount she charges per hour for each dog and then multiply it by the total number of hours.
First, let's determine the amount she charges per hour for each dog. Since Su-Lin charges $1.50 per hour per dog, multiply $1.50 by the number of dogs she is walking, which is 2.
$1.50/dog/hour * 2 dogs = $3/hour
Next, we need to find the total number of hours Su-Lin is walking for. The given information states that she is walking the dogs for 1 1/2 hours. To calculate this in decimal form, we need to add 1 + 1/2 = 1.5 hours.
Now, multiply the amount she charges per hour by the total number of hours:
$3/hour * 1.5 hours = $4.50
Therefore, Su-Lin will make $4.50 for walking the dogs for 1 1/2 hours, not $3.
