Jackie wants to take out an ad in the newspaper for her upcoming garage sale. She can buy a 4-line ad for $4.35 that will run for three days. If she wants to spend no more than $15 on advertising, how long can she advertise?

She can advertise for 10 days

Step-by-step explanation:

Here, we want to know for how long can Jackie advertise if she decides to buy a 4-line ad which will run for three days.

The total money she has or she wants to spend is $15.

Now if $4.35 will run for 3 days

then $15 will run for x days

4.35 * x = 15 * 3

4.35x = 45

x = 45/4.35

x = 10.34 which is approximately 10 to the nearest whole number
