5. While still in the hospital, the doctor writes an order for an antibiotic at 300mg/kg daily. You are nervous now because the
Scilla [17]

The correct answer is 16737 mg

Explanation:

The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:

123 lb x 0.453 = 55.791 kg

Now, simply multiply the kilos by the recommended dose:

55.791 kg x 300 mg/kg = 16737 mg

Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)

16737mg ÷ 1000 =  16.737 grames

Ben needs to buy orange juice. He can buy 64 fl oz at the grocery store for $2.00, or he can buy 256 fl oz at the wholesale club
sp2606 [1]
I would love to help you but I'm not at home rn basically, divide the price by amount. ex: ($)price/amount(fl oz) . do it for both store and round to thousandths and the one with the less price is the best deal. so... I apparently have some time to solve this for you, so let me begin :) just to give you an idea, I'll solve the grocery one for you! 2/64 = 0.03125 = $0.0313 per Fl Oz. solve the next one with the equation and compare to see which is lower. Explaining part, stating that the one has lower price will do.
