A company is holding a retirement party and is ordering sandwich wraps and hamburgers. The cost of one sandwich wrap and one hamburger is $8. The company originally orders 25 sandwich wraps and 50 hamburgers at a cost of $325, but based on the number of people planning to attend the party, the company decides to revise the order. Which of the following revised orders will result in the same cost per sandwich wrap and same cost per hamburger as the original order, assuming that the cost of one sandwich wrap and one hamburger is still $8? Select three that apply. ordering 33 sandwich wraps and 58 hamburgers at a cost of $333 ordering 15 sandwich wraps and 40 hamburgers at a cost of $245 C. ordering 75 sandwich wraps and 100 hamburgers at a cost of $725 ordering 50 sandwich wraps and 25 hamburgers at a cost of $325 E ordering 26 sandwich wraps and 51 hamburgers at a cost of $333

answer:

idk but thx for free point

ddd

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
