The cost of renting a moving van for a 26 mile trip is $62.50. the cost of renting the same van for a 38 mile trip is $65.50 The
Darya [45]
The difference between the 26 mile trip and 38 mile trip is 12 miles.
The difference in the price is $3.00   ($65.50 - $62.50)

So those 12 miles cost $3.00     $3.00÷12 = $.25 per mile

We can use either given trip to solve.  I will use the 38  mile trip.
The difference between 38 miles and 54 miles is 16 miles.   At $.25 a mile those 16 miles will add $4.00 to the price.  ($.25 x 16 = $4.00)
Since the 38 mile trip costs $65.50 we add $4.00 and get $69.50 for a 54 mile trip.

There are 10 kids on the math team. Two kids will be selected from the team to compete in the state competition. How many ways a
patriot [66]

Answer:

45 ways

Step-by-step explanation:

Total number of kids = 10

We have to select the 2 kids

So the number ways to select two kids ^{10}C_2

We know that ^{n}C_r=\frac{n!}{r!(n-r)!}

So ^{10}C_2=\frac{10!}{2!(10-2)!}=\frac{10!}{2!\times 8!}=\frac{10\times 9\times 8!}{2\times 8!}=45

So there are 45 ways to select 2 competitors
