Louise mowed a neighbour's yard to earn $25. She mowed a few more yards and earned an additional $75. She continued to mow all of the yards each week for a total of 555 weeks, earning money at the same rate. At the end of the 555 weeks, she spent $250.
Which numerical expression shows the amount of money Louise has left?
Choose 1 answer:
(Choice A)
5x (25 + 75) - 250
(Choice B)
250−(5×25)+75
(Choice C)
C
(5x25) + 75 - 250
A Is Correct
PsyDAG, It was supposed to be 5, sorry for confusing you.
Unless you have a typo, it would be 555 (25+75) - 250 = ?
SAVE THE TURTLES!!
To find the amount of money Louise has left, we need to subtract the amount she spent from the total amount she earned.
First, let's calculate the total amount she earned. She earned $25 for mowing the neighbor's yard and then an additional $75 for mowing more yards. So, the initial amount earned is $25 + $75 = $100.
Next, we need to calculate the total amount earned for 555 weeks. Since she earned money at the same rate each week, we can multiply the initial amount ($100) by the number of weeks (555). This gives us $100 x 555 = $55,500.
Now, we can find the amount of money Louise has left by subtracting the amount she spent ($250) from the total amount earned ($55,500).
Using the given numerical expressions, let's evaluate each option:
(Choice A) 5x (25 + 75) - 250:
To evaluate this expression, first calculate the value inside the parentheses: 25 + 75 = 100.
Then multiply it by 5: 5 x 100 = 500.
Finally, subtract 250: 500 - 250 = 250. So this expression evaluates to 250, which is incorrect.
(Choice B) 250 - (5 × 25) + 75:
To evaluate this expression, first calculate multiplying inside the parentheses: 5 x 25 = 125.
Then subtract it from 250: 250 - 125 = 125.
Finally, add 75: 125 + 75 = 200. So this expression evaluates to 200, which is incorrect.
(Choice C) (5 × 25) + 75 - 250:
To evaluate this expression, first multiply: 5 x 25 = 125.
Then add 75: 125 + 75 = 200.
Finally, subtract 250: 200 - 250 = -50. So this expression evaluates to -50, which is incorrect.
None of the given options evaluate to the correct answer. So, the correct numerical expression is not provided in the given choices.
