Answer: 115% increase
Step-by-step explanation: To solve, we need to subtract the first value fro the second value. The formula is Percent Change = ((Second Value – First Value) ÷ First Value) x 100%
700,000-326,000=374,000. Then, divide the difference by the first value.
374,000÷326,000=1.1472392638≈1.15
1.15×100%=115%
Thus, the approximate percent of increase in the bales produced during that 21-year period is 115% increase
