------
 16,22  slope = y/x = 22/16 = 11/8

amistre64 · Answer

f = (11/8)c + b

56 = 11(8)/8 + b

56 = 11 + b

45 = b

the equation should be...barring any stupidity on my part...

f = (11/8)c + 45

amistre64 · Answer

when c = 72; f = 11(72)/8 + 45

f = 792/8  +45

f = 99 + 45 = $144
