Question 1188417
Let x be the cost of the large van, and y be the cost of the small van. We have the system of equations {{{system(4x+2y=160000,2x+3y=128000)}}}.
*[invoke linear_substitution "x", "y", 4, 2, 160000, 2, 3, 128000] 
Therefore, the cost of the large van is $28,000 and the cost of the small van $24,000.
