From the statement we know that dog's weight is 12 kg, and daily injections are required for 3 days, the dose rate is 7.5 mg/kg, so we need to calculate how many mL per injection does Benji require.
We have that:
If the dose rate is 7.5 mL per each Kg, how many mL are required for 12 Kg? We can set it up using the following relation:
Hence, we have that there are needed 90 mL per injection.
Step-by-step explanation: We have to find what is 15% of $375.00 so we change the percentage to a decimal so and multiply so .15 X 375.00 = $47.25 so then we already had a bill of 375.00 so we add $375.00 + $47.25 and our grand total is $422.25
