i need solving this equation.

select the appropriate equation that solves the problem. then solve the equation.

brandy wants to buy a digital camera that costs $300. suppose she saves $15 each week.

in how many weeks will she have enough money for the camera? use an equation to solve algebraically.

a) choose the correct equation:
which one is correct?
equation: 15 + w = 300
w/15 = 300
15w = 300
w - 15 = 300

b) solve the chosen equation:

w = the number of weeks needed to save for the $300.

when you solve the correct equation w = ? weeks
