It cost $9 to go to pete's pottery place to make your own bowls for $3 per bowl. natalie goes to pete's pottery place and makes b bowls. she decides to make bowls 5 days this month so she can sell them at a craft fair.

part a: write an expression that will represent natalie's total cost for this month.

part b: if she makes 4 bowls each time she goes to pete's pottery place, what will her total cost be?

A) total cost = 3b+(9*5)

B)

she makes 4 bowls every visit (5) so 5*4 = 20 total bowls

total cost = 3(20) +(9*5) = 60+45= 105 dollars

i got 10.28 but that rounds up to 10.3

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.
