Sally gets paid $15.00 dollars per hour for a 40-hour work week and y dollars for each hour she works over 40 hours. What is the
Anna35 [415]

The equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.

<u>Step-by-step explanation:</u>

  • Sally gets paid $15.00 dollars per hour for a 40-hour weekly work.
  • She gets y dollars for each extra hour she works over 40 hours.

<u>The equation can be framed as :</u>

Let,

  • x be the total pay she could get for 48 hours.
  • The amount she earned for 40 hours = 40 × $15 ⇒ $600
  • The amount she earned for extra hours = 8 × y ⇒ 8y

The equation is given as,

Total earnings = amount earned for 40 hours + amount for extra 8 hours.

⇒ x = 600 + 8y

Therefore, the equation x = 600 + 8y represents the earnings of Sally if she works 48 hours.
