Well my answer (only part a) is 216 and not 252 if thats what the answer key said
I do believe that the answer key is wrong because...
when u take
252÷6 = 42 (number of long ruler packs)
42 × 8 = $336 (cost for long rulers)
252 ÷4 = 63 (number of short ruler packs)
63 × 3 = $189
Difference in cost : 336 - 189 = 147 (not equal to 126 which was given in the qn)
If its a hw do clarify with ur teacher but if its assessment book uhh dont trust assessment books blindly!
