After 1 h it has $42.75. after 5 h, it has $260.75. how much money will it be in the register
at the end of an 8-hour shift

If he has 42.75 in an 1hr shift, the if he has 260.75 on an 5hr shift. what you would do to figure out how much he made in an 8hr shift is?

you would do 260.75 + 42.75= 303.50 that is what you get for an 6hr shift.
to find your 7hr shift you would do 303.50+42.75= 346.25.
to find the final awnser you would do 346.25+42.75=389.00.
so he would make $389.00 on an 8hr shift.

hope this helps

B.the point lies directly on the regression
