x ≈ 114
I think it is 45.00 because you multiply -4.50 x 5= -22.5. The reason you multiply x4.59 times 5 is because he takes away 4.50 every day for 5 days. And then you do 67.50-22.5=45.00.
<span>If tickets for the upper deck are 75% of the cost of tickets for the lower deck and lower deck tickets are $42, then tickets for the upper deck $31.50 each. Therefore the answer cannot be A or C, because both of those options misstate the cost of the upper deck ticket. The answer also cannot be D, because it expresses the inequality when the combined number of tickets is greater than $800, which is not what was asked for.
