A small company has one color printer and one black-and-white printer, each printing at different rates. The color printer, working for 5 minutes and the black-and-white printer, working for 3 minutes print a total of 70 pages. When the black-and-white printer worked for 6 minutes and the color printer worked for 9 minutes, they printed a total of 135 pages. This situation is represented by the equations below, where b represents the number of pages per minute printed by the black-and-white printer and c represents the number of pages per minute printed by the color printer.

How many pages per minute does the black -and- white printer print?

A. 11 B. 12 C. 15 D. 18

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

only 10/60 isn't equivalent

hope this : )

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
