A survey of voters explored the relationship between the ages of voters and wether or not they support building skateboard ramps at a local park.

Ages 18-37: In Favor-40 Opposed-10 Total-50
Ages 38-57: In Favor-27 Opposed-23 Total-50
Ages 58 and over: In Favor-6 Opposed-44 Total-50
Total: In Favor-73 Opposed-77 Total-150

Round answers to the nearest whole percent.

a. What percentage of surveyed voters in the 58 and over age group are in favor to building skateboard ramps?

b. What percentage of surveyed voters in the 18-37 age group are opposed of building skateboard ramps?

c. What is the percentage of the total number of people that are in favor to building skateboard ramps?

Please be fast! Thank you so much!

(a)12%

(b)20%

(c)49%

Step-by-step explanation:

(a)In the age group 58 and above:

Percentage of those in favor =

(b)In the age group 18-37

Percentage of those opposed to it =

(c)

Percentage of those in favour =

i dont know

step-by-step explanation:

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.
