9. At the factory where he works, Mr. Lopez must make a minimum of 48 circuit boards per day. On Wednesday, he made 60 circuit boards. What percent of the required minimum did he make?
Answer: A
Mr. Lopez made 125% of the required minimum circuit boards.
To determine the percent of the required minimum that Mr. Lopez made, we calculate the ratio of the number of circuit boards he produced to the minimum required and then convert that ratio to a percentage. He made 60 circuit boards, which is 125% of the minimum requirement of 48 circuit boards.
A) 125%
This option is correct because it accurately represents the calculation: (60 / 48) * 100 = 125%. This shows that Mr. Lopez exceeded the minimum requirement by 25%.
B) 112%
This option is incorrect as it suggests that Mr. Lopez produced only slightly more than the required minimum. The calculation for 112% of 48 circuit boards would be 53.76, which is less than the 60 he actually made.
C) 80%
This option is incorrect because it indicates that Mr. Lopez made significantly less than the required minimum. 80% of 48 circuit boards would equal 38.4, which is far less than the 60 he produced.
D) 25%
This option is also incorrect as it denotes a very small percentage of the required minimum. 25% of 48 circuit boards equals 12, which is much lower than the 60 circuit boards made by Mr. Lopez.
Conclusion
Mr. Lopez’s production of 60 circuit boards represents 125% of the required minimum, confirming that he not only met but exceeded the minimum expectations significantly. All other options misrepresent the actual percentage of the minimum requirement he fulfilled, making them incorrect.
