I have 2 math problems and have no idea how to solve them:
#1. Bernadette's math test has 14 sections. Each section has either 8 or 12 problems. How many sections are there of each size if the test is 132 problems long?
#2. A moving truck rental company has a total of 24 trucks in its lot. The trucks are either 4-wheelers or 18-wheelers. How many of each kind of truck does the company have if the total number of wheels is 138?
I need to show the work. Thanks so much for any help that you can provide.
