Tara baked 6 1/2 dozen cookies. she sold 3 2/6 dozen of the cookie she made. how many dozens of cookies does tara have remaining

One dozen has 12 units.

So 6 and a half dozen shall have 6.5 ×12 = 78 cookies.

She sold

dozens

So cookies she sold

=

Number of cookies left = 78 - 40 = 38

So 38 cookies

Tara is left with dozens

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.
