Agrocery delivery service charges $0.80 per mile and a set fee of $5.40.

which function models this situation?
a. y = 0.8x + 5.4
b. y = –0.8x + 5.4
c. y = 5.4x + 0.8
d. y = 5.4x – 0.8

i think its either a or c

A.y = 0,8x + 5,4

Step-by-step explanation:

$0,80 per mile indicates multiplication, so that gets an x, while adding this to the fee of $5,40.

I am joyous to assist you anytime.

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.

the answer is 40.
