With black ink      ⇒⇒⇒ <span>b(t)=152-33t
With </span>colored ink   ⇒⇒⇒ <span>c(t)=152-30t

After 1 minute :
b = 152 - 33 * 1 = 152 - 33 = 119
c = 152 - 30 * 1 = 152 - 30 = 122
c - b = 122 - 119 = 3

The correct choice is:
</span><span>G. The printer prints 3 fewer pages per minute in black ink than in colored ink.</span>
