Question

PLEASE HELP!!!! I WILL GIVE BRAINLIEST!!!!

Answer 1

1.not first one because Bella's rate is 3.5 and Sweet T's is 2
2. 3.5*5+11=17.5+11=28.5 -after doing 5 chores - for Bella
   after 5 chores (for Sweet T's)  20
not this one
3. y =ax +b
for Sweet T: d=2c+b, (1,12),  12=2*1+b,  b=10 , d=2c+10,
when c=0 ,d=10 initial saving for Sweet T
for Bella : d=3.5c+11, when c=0 , d=11 initial saving
initial saving of Bella is more 11>10
so not this one
4. so we have only one left, Bella saves per chore 3.5 and Sweet T saves per
 chore 2. Bella save more per chore than Sweet T
this should should be correct answer
