Your store has an average time of 90 seconds to process a sales transaction. there are three customers in line to check out. how much time will have passed when the last sales transaction is complete? a) 4.5 minutes b) 5 minutes c) 6.25 minutes d) 8 minutes

The answer is A. because first, you need to multiply 90 times 3 which will equal 270 seconds. Then, once you divide the seconds by 60 to figure how many minutes 270 seconds is, you get 4.5 minutes.

answer: 12

step-by-step explanation:

because yes

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
