Answer:
Lisa earns more money because John makes $16 while Lisa makes $18.
1/3 is greater than 1/5 and 1/4.
The proportion equal to a/b = c/d is A.) A/C = B/D
We will know if a proportion is equivalent when its cross products are equal.
a/b = c/d where ad = bc
since ad = bc, a/c = b/d
-2(5)^2+2(5)-3
-2(25)+10-3
-50+10-3
-40-3
=-43
