Answer: 17.5%
Step-by-step explanation:
Percentage of chips given to Jackie = 20%
Percentage of chips given to Ronald = 20%
Percentage of chips given to Mark = 1/4 × 100 = 25%
From the above calculation, we can see that Ms Johnson has given out ((20% + 20% + 25%) = 65% worth of chips out. The percentage she'll have left will be:
= 100 - 65
= 35%
Since Susan takes half of what's left, the percent that Ms. Johnson has left to eat will be:
= 1/2 × 35%
= 17.5%
She has 17.5% left to eat.
