Question

PLEASE HELP ME!! I ALREADY DID THE FIRST ONE BUT IM SO CONFUSED ABOUT THE OTHERS!!!

Answer 1

i) 134

ii) Number of bottles sold on Tuesday:
`(x)/(45)`

iii) Number of bottles sold on Wednesday:
`((x-75))/(48)`

iv)
`x=3915`

Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday

Explanation:

i) You need to ensure that the values are both in the same format (either both in dollars, or both in cents).

45 cents = 45/100 dollars = 0.45 dollars

60.30 ÷ 0.45 = 134

ii) both values are in cents, so no need to convert one of them.

Let n be the number of bottles sold.

So 45n = x

Therefore, n = x/45

ii)

Let n be the number of bottles sold.

So 48n = (x - 75)

Therefore, n =
`((x-75))/(48)`

iv)

Number of bottles sold on Tuesday:
`(x)/(45)`

Number of bottles sold on Wednesday:
`((x-75))/(48)`

If the number of bottles sold on Tuesday was 7 more than those sold on Wednesday:

`\implies (x)/(45)-7=((x-75))/(48)`

multiply both sides by 48:

`\implies (48x)/(45)-336=x-75`

multiply both sides by 45:

`\implies 48x-15120=45x-3375`

`\implies 3x=11745`

`\implies x=3915`

Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday
