Answer:
981/100
Step-by-step explanation
step: 9.81= 9.81/1
step 2 multiply both too and bottom by 10
9.81/1 = (9.81*100)/(1*100)= 981/100
thus 981/100 is also equal to 9 81/100
Take 4,000 times 12 to get 48,000. that’s how much A costs.
B is a little harder. you have to take (2,300+300)x12+(4*250). this equals $32,100
the correct answer would be B.
