Answer:
The answer is 80%.
Step-by-step explanation:
During a certain day, a worker made 81 parts.
He usually does 45 parts per day.
Number of extra parts made = [tex]81-45=36[/tex]
The percent by which he increased the number of parts he usually makes can be given as = [tex]\frac{36}{45}\times100[/tex] = 80%
Therefore, on that day, the percent increased by 80%.
Answer:
Increase by 80%
Step-by-step explanation:
45 : 100%
81 : y
[tex]\frac{81}{45} :\frac{y}{100}[/tex]
y × 45 = 81 × 100
45y = 8100
45y ÷ 45 = 8100 ÷ 45
y = 180
180% - 100% = 80%
Increase by 80%
