+129899 a 40v + 15d ≤ 175
b 40(2) + 15d ≤ 175
80 + 15d ≤ 175 subtract 80 from both sides
15d ≤ 95 divide both sides by 15
d ≤ 6 + 1/3 but d must be a whole quantity....so.....d = 6
He can buy - at most - 6 DVDs
c No DVDs..solve this
40 v ≤ 175 divide both sides by 40
v ≤ 4 + 3/8........... ⇒ 4 video games
(t)1(e)+(s)49(T)=(03)50
