For the second question, the answer would be A because the lines intersect at 2 and -1.4. For the first question, t+b is less than or equal to 20 and 15b+8b is greater than or equal to 150 is the answer because Nick can work <u>up to </u>20 hours and needs to make <u>at least</u> $150 per week so that answer fits best. That question is solved mostly by context clues.
