Step-by-step explanation:
40 increases to 56.
To find the percent increase:
Subtract the increased value from the original value.
Divide the difference by the original value.
Multiply the quotient by 100 to represent the percent.
Solve:
[tex]56 - 40 = 16[/tex]
[tex]16 \div 40 = 0.4[/tex]
[tex]0.4 \times 100 = 40[/tex]
There's a 40% increase.
