Problema Solution
tom and Jerry are undercover sales animals for a company called "Security against owners." Last week Tom sold 12 fewer weapons then Jerry did. Together they sold 44. How many did each sell?
Answer provided by our tutors
let
t = the number of weapons Tom sold
j = the number of weapons Jerry sold
Last week Tom sold 12 fewer weapons then Jerry did:
t = j - 12
Together they sold 44:
t + j = 44
by solving the system of equations:
t = j - 12
t + j = 44
we find:
t = 16 weapons
j = 28 weapons
