Jamie bought a soda for $3. he also bought some corn dogs for $4 each. jamie did not spend more than $27 on the corn dogs and the soda. which inequality can be used to find h, the number of corn dogs that jamie could have bought?
a) 4c + 3 ≤ 27
b) 4c − 3 ≤ 27
c) 4c + 3 ≥ 27
d) 4c − 3 ≥ 27

step-by-step explanation:

a because she did not spend more than $27

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.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
