Answer:
i) 134
ii) Number of bottles sold on Tuesday: [tex]\dfrac{x}{45}[/tex]
iii) Number of bottles sold on Wednesday: [tex]\dfrac{(x-75)}{48}[/tex]
iv) [tex]x=3915[/tex]
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 = [tex]\dfrac{(x-75)}{48}[/tex]
iv)
Number of bottles sold on Tuesday: [tex]\dfrac{x}{45}[/tex]
Number of bottles sold on Wednesday: [tex]\dfrac{(x-75)}{48}[/tex]
If the number of bottles sold on Tuesday was 7 more than those sold on Wednesday:
[tex]\implies \dfrac{x}{45}-7=\dfrac{(x-75)}{48}[/tex]
multiply both sides by 48:
[tex]\implies \dfrac{48x}{45}-336=x-75[/tex]
multiply both sides by 45:
[tex]\implies 48x-15120=45x-3375[/tex]
[tex]\implies 3x=11745[/tex]
[tex]\implies x=3915[/tex]
Therefore, 87 bottles were sold on Tuesday and 80 bottles were sold on Wednesday
