On thursday bernies dog ate 1/4 lb more dog food than she ate on wednesday. on wednesday, the dog ate 1 1/3 times the amount of food she ate on tuesday. if bernie's dog ate 1 3/4 lb food on thursday, how much did she eat on tuesday?

"On Thursday Bernie's dog ate 1/4 lb more dog food than she ate on Wednesday."

That means that on Wednesday, the dog ate 1/4 lb LESS that it ate on Thursday.

"On Wednesday, the dog ate 1 1/3 times the amount of food she ate on Tuesday."

That means that on Tuesday, the dog ate 1 1/3 times LESS that it ate on Wednesday.

Now start with Thursday: "If Bernie's dog ate 1 3/4 lb food on Thursday"

On Wednesday it ate 1/4 lb less that that, so on Wednesday it ate

1 3/4 - 1/4 = 1 2/4 = 1 1/2

On Wednesday it ate 1 1/2 lb.

On Tuesday it ate 1 1/3 times less than on Wednesday. Now we divide 1 1/2 by 1 1/3.

It ate 1 1/8 lb of food on Tuesday.

its 50 miles away from the starting point

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 ☺
