Question

How many weeks of flea treatment would Jim’s dog get from one package if each treatment only lasted 3 weeks In a normal year when a flea treatment last 4 weeks how many more weeks of treatment would Jim’s dog get from one package. Each flea treatment usually last for about 4 weeks but one year the fleas were especially bad Jim’s dog needed to be treated for fleas every 3 weeks until the weather cooled off

Answer 1

Solution

Number of weeks in a year = 52 weeks

If in a normal year when each package of flea treatment lasts for 4 weeks, then in a year there Jim's dog will have to be treated for

$\frac{52}{4} =13 times$

Where as, when the fleas are bad in a year, the treatment lasts for only 3 weeks.

Then in a year Jim's dog would get

$\frac{52}{3} =17 times$

So Jim's dog will get 17- 13 =4 treatments more.

4 treatments that are made in 3 weeks each will be 4×3 =12 weeks more treatment
