Question 1201573
higher priced speaker dock is 1900.
lower price speaker dock is 800.
last week store sold 3 times as many lower priced speaker docks as higher priced speaker docks.
let x = number of lower price speaker docks.
let 3x = number of higher price speaker docks.
you get 3x * 800 + x * 1900 = 34400.
combiine like terms to get 2400x + 1900x = 34400.
combine like terms to get 4300x = 34400.
solve for x to get x = 8.
they sold 24 lower price speaker docks and 8 higher price speaker docks.
total sales is 24*800 + 8*1900 = 19200 + 15200 = 34400.
solution is they sold 24 lower priced docks.
