Problema Solution

Two factory plants are making tv panels. Yesterday plant A produced 4000 fewer plants than plant B did. 3% of the plant from plant A and 5% of panels from plant B were defective. How many panels food plant A produce if the two plants together produced 1320 defective panels?

Answer provided by our tutors

let


a = the number of panels produced in plant A

a + 4000 = the number of panels produced in plant B


3% of the panels from plant A and 5% of the panels form plant B were defective and the plants together produced 1320 defective panels


0.03a + 0.05(a + 5000) = 1320


by solving we find


a = 13,375 panels
