Solution

a. Cost will be more because 1.075 is greater than 0.1.

Thus none of these is the correct answer.

b. h(t)=1.075t+0.1t+t

Or. h(t) = 2.175t. Ans.

c. i) Pre-tex subtotal = 1.5/0.1 =$15. Ans.

ii) cost =1.075*15=16.125

Total cost =16.125+15+1.5=$32.625. Ans.

d. p =1.075*(d/0.1)+d/.01+d

=10.75d+10d+d

p=21.75d. Ans.
