The high school jazz band is selling homemade leather bracelets at a local craft fair to raise money for a trip. The group spent $200 on supplies, which is enough to make 260 bracelets. The group is charging $2 per bracelet at the craft fair. Suppose b is the number of bracelets sold, and f(b) is the profit the band makes on the sales. Write a function modeling the relationship.

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.

its an acute right triangle
