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

A. y = 0.8x + 5.4

Step-by-step explanation:

Make each mile be represented by the variable x, therefore the $0.80 per mile will be represented by 0.8x. The set fee is always going to be there for each time you order, so you will just add 5.40 to 0.8x.

The function is y = 0.8x + 5.4.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
