<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.
The correct answer is B. 42x + 31.5y ≤ $800. This gives the correct price for upper deck tickets and expresses the correct inequality.</span>

Step-by-step explanation:
h(5) = 5 - 7 = -2
g(-2) = (-2)^2 = 4
Answer:
0.6845% per week.
Step-by-step explanation:
Simple Interest Calculation A = P(1 + rt)
Solving our equation:
r = (1/730.5)((15000/2500) - 1) = 0.00684463
r = 0.00684463
Converting r decimal to R a percentage
R = 0.00684463 * 100 = 0.6845%/week
Calculating the annual rate
0.6845%/week × 52 weeks/year = 35.594%/year.
The interest rate required to get a total amount, principal plus interest, of $15,000.00 from simple interest on a principal of $2,500.00 over 14.05 years (730.5 weeks) is 0.6845% per week.
F=x-48 over 4x. I hope that is right :)
