It takes a printer 2 1/2 min to print 24 black-and-white pages and 4 color pages. It takes the same printer 3 1/4 min to print 3

Paul [167]

Multiply the first equation by 1.5, to get:
$(1.5)(24b + 4c) = 1.5(2.5)$
$36b + 6c = 3.75$
Subtract the second equation from this:
$6b = 1/2$
$b = 1/12$
Substituting into the first equation:
$24b + 4c = 2.5$
$24*(1/12) + 4c = 2.5$
$2 + 4c = 2.5$
$4c = 0.5$
$c = 1/8$
Therefore, it takes 1/12 minute to print a black-and-white page, and 1/8 minute to print a colored page.
