Question

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

Answer 1

Answer:

i) 134

ii) Number of bottles sold on Tuesday:   $\dfrac{x}{45}$

iii) Number of bottles sold on Wednesday:  $\dfrac{(x-75)}{48}$

iv) $x=3915$

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

Step-by-step 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 = $\dfrac{(x-75)}{48}$

iv)

Number of bottles sold on Tuesday:   $\dfrac{x}{45}$

Number of bottles sold on Wednesday:  $\dfrac{(x-75)}{48}$

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

$\implies \dfrac{x}{45}-7=\dfrac{(x-75)}{48}$

multiply both sides by 48:  

$\implies \dfrac{48x}{45}-336=x-75$

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
