Max has $125 consisting of bills each worth either $5 or $20. How many bills worth $5 does Max have?
(1) Max has fewer than 5 bills worth $5 each
OG says to (1): Given that x<5, then x=0, 1, 2, 3, or 4.
My question is not about the solution of this exercise, but about the explanation of OG: why could x be 0? It is written that Max has $125 consisting of bills each worth either $5 or $20. --> at least for me, this means, that Max has at least one $5 bill and at least one 20$ bill?
does anybody agree?
