Hi there! The formula for simple interest is prt. That means multiply the principal (initial amount) by the rate (simple interest rate) by the time (could be in months or years). In this case, we multiply 475 * 5% (0.05) to get 23.75. That's $23.75 in interest each year, but we're looking for the amount earned in 10 years. To do this, multiply 23.75 by 10. When you do, you get 237.5. There. $237.50 in interest will be earned in 10 years.
Answer: Attached.
Step-by-step explanation:
Either solve the equations directly, or graph them and look for the point of intersection.
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.
