100 adults were asked about their favorite food. 75 said they liked hamburgers, 65 said they liked chips, 85 said they liked pizza. Determine the fewest possible number of adults who could have said they liked all three foods? Please help, thank you so much

The least # of people that liked all 3 is 25.

Step-by-step explanation:

To determine the least possible number of people that liked all 3, you have to subtract the people that didn't like it. Like this --->>> 75-(100-85),75-15,60 people that had to have liked pizza and hamburgers. 60-(100-65), 60-35, 25. Or the much easier way, add up all of the people that didn't like them, like this. >>> 100-((100-75)+(100-85)+(100-65))=100-(25+15+35)=100-75=25

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
