Solve the problem using matrices.

There were approximately 100 vehicles sold at a particular dealership last month. The dealer tracks sales by age group for marketing purposes. The number of 36- to 59-year-old buyers and the number of buyers 60 and older combined exceeds the number of buyers 35 and younger by 28. If the number of buyers in the oldest group is doubled, it is 25 less than the number of users in the middle group. Find the number of buyers in each of the three age groups.
◦ 36, 35 and younger; 51, 36-59 year olds; 13, 60 and older
◦ 38, 35 and younger; 48, 36-59 year olds; 14, 60 and older
◦ 30, 35 and younger; 53, 36-59 year olds; 17, 60 and older
◦ 13, 35 and younger; 51, 36-59 year olds; 36, 60 and older
