Question 1172253
the play station costs 400
he has 125 saved up so far.
he makes 5 per hour for helping out with chores around the house.
the equation to solve this is:
y = 125 + 5x
y is the amount of money he needs to save up for.
x is the number of hours he works.
since y = 400, the equation becomes:
400 = 125 + 5x
subtract 125 from both sides of this equation to get:|
275 = 5X
divide both sides of this equation by 5 to get:
275/5 = x
solve for x to get:
x = 55 hours.
confirm by replacing x in the original equation with 55 to get:
400 = 125 + 5 * 55
simplify to get:
400 = 400
this confirms he solution is correct.\
the solution is the he needs to work for 55 hours to get a total of 400 dollars saved up so that he can purchase the play station III.
