2. Railyn is saving for a laptop computer. She already has
$800 saved and plans to save $50 a week from her baby
sitting money. If the laptop she wants costs $1,150, how
many weeks will it take her to save enough to buy it?
a. Define the variable and represent the situation with
an equation.

Respuesta :

x = number of weeks which is some positive whole number

50x = amount saved after x weeks, when saving $50 per week

50x+800 = add on the 800 she already has

The expression 50x+800 is the total money saved. We set this equal to the 1150 to set up the equation we're after

Answer:  50x+800 = 1150
