Answer: 75%
Step-by-step explanation:
1. You know that the diameter of mature grapes increased from 1.0 centimeters to 1.75 centimeters.
2. Then, to calculate the percent increase in size, you can apply the following formula:
[tex]\%increase=(\frac{new\ amount-original\ amount}{original\ amount})*100\\\\new\ amount=1.75cm\\original\ amount=1.0cm[/tex]
3. Therefore, when you substitute the values shown above into the equation. Then, you obtain that the percent increase in size is:
[tex]\%increase=(\frac{1.75cm-1.0cm}{1.0cm})*100[/tex]
[tex]\%increase=75\%[/tex]
