An electronics shop offers a small ic chip for $1.50 per unit and $4.00 for large ic chip. on a certain day, 2200 chips were sold and $5050 is collected. how many small ic chips and how many large ic chips were sold?
Let s and l represent the numbers of small and large ICs sold that day. The problem statement gives rise to two equations. .. s + l = 2200 .. 1.50s +4.00l = 5050
Solving these by your favorite method gives .. s = 1500 .. l = 700
