At the bookstore checkout, you watch as the register rings up your purchases and coupons. the prices were as follows: $1.85 $8.56 $6.30 $2.73 $5.25 $4.09 $7.95 – $0.85 (coupon) – $2.10 (coupon) the register gives your total bill as $41.44. estimate the total amount of the bill, by rounding each value to the nearest dollar, and use your answer to determine whether the total on the register is reasonable.

2.00+9.00+6.00+3.00+5.00+4.00+8.00-1.00-2.00= $34.00$1.44 - 34.00 

41.44 - 34.00 = 7.44
The difference is $7.44, therefore the amount on the register is not reasonable.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
