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.
garden: Area = 7 x 4 = 28
plants: Area = 1 x 1 x 30 plants = 30
30 - 28 = 2
Answer: 2 plants
Error=100 calculated/actual
error=100 (175-97.5) / 97.5
error=100 (77.5) / 97.5
error=7750 / 97.5
error=77500 / 975
error=3100 / 39
error=79.5% <-- Estimated
