A hotel cost $89 per night. sally will receive a $5 per night discount for paying in advance.a rental car cost $35 per day plus
natulia [17]
You can multiply both 89 and 5 by both 5 because it's over a course of 5 days, than subtract the total by each other. For the rental you have to multiply ,35 by 5 and 4 than add those two sums together. Once you have all the totals, add them all together to get your answer

Select the favorable outcomes for rolling a sum less than five
Anvisha [2.4K]
We want the sum of the two rolls to be less that five.
Therefore, we will examine each given set of choices and choose the one where all the points have a sum less than 5.

First set: all the point are 5 added to another number. Therefore, the sum is definitely not less than 5. This choice is rejected.

Second set: We have two points having 6 added to a number. Therefore, this choice is also rejected.

Third set: We have the points (5,5) and (6,6) which have a sum greater than 5. Therefore, this set is also rejected.

Fourth set: We have:
(1,1) with sum = 2
(1,2) with sum = 3
(1,3) with sum = 4
(2,1) with sum = 3
(2,2) with sum = 4
(3,1) with sum = 4
Therefore, all sums are less than 5. This is the correct choice.

Based on the above, the correct option is the last one.
