11/4 pounds = 2,75 pounds = 2,75 pounds x 2$ + 2,5 pounds x 1,50$ = 5,50$ + 3,75$ = 9,25 $
Total Cost: 9,25$
We need a system of equations here, one equation based on the NUMBER of tickets sold and another based on the MONEY earned by the sales. We have 2 different types of tickets: full price (f) and discount (d). The total number of tickets sold is 428; therefore, the first equation is f + d = 428. That accounts for the number of tickets sold. Each full price is 10.25 which can be represented as 10.25f, and each discount ticket costs 8 which can be represented as 8d. The money earned by selling these tickets at those prices was 3946. That means that the second equation is 10.25f + 8d = 3946. We will solve the first bolded equation for f to get f = 428 - d. Sub that value in for f in the second bolded equation: 10.25(428-d) + 8d = 3946. Distribute to get 4387 - 10.25d + 8d = 3946. Combine like terms to get -2.25d = -441. Solving for d we get 196. That means that there were 196 discounted tickets sold. Put that in for d in the first bolded equation to find the number of full price tickets. f + 196 = 428, and f = 232. There were 232 full price tickets sold. There you go!
Nope, you wouldn’t be breaking the speed limit because 60km/h converted into miles is just 37.3mi/h, which is perfectly fine in the speed limit.

Answer:
The 16th term is 91
Step-by-step explanation:
The 16th term is U16 given by
U16=a+(n-1)d
U16=1+(16-1)×6
U16=1+(15×6)
U16=91
