At Trent's garage, 3 cases of brake fluid last 4 weeks. Trent has 5 cases. How much more brake fluid should Trent order so that he has enough for 13 weeks? Round your answer up to the nearest whole number.

Question

3 cases last for 4 weeks which means one case lasts for slightly more then one week.

This means that 3 times 3 cases would last 12 weeks, one more case for week number 13.

 So he would need 10 cases altogether. He already has 5 so he would need to order 5 more.
