The given ratio is:

To find the unit cost per ounce, we can use proportions as follows:

Now, solve for x:

The cost per ounce (unit cost) is then $0.12/oz
Answer:
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.
Step-by-step explanation:
Given that,
Holly has $462 in her bank account and takes out $15 each week but does not put any back in.
She takes out $15 on first week.
The remaining amount of her bank account is =$(462-15)
=$(462 - 1×15)
If she withdraws $15 on second week.
The remaining amount of her bank account is =$(462-15-15)
=$(462 - 2×15)
Similarly after third the amount in her account is =$(462 - 3×15)
From the above it is cleared that
The amount in her account after t week is
=$(462 - t×15)
Therefore required expression is
y =462 - t×15
where y represents the amount of money in her bank account in dollar after t week.


The product of any integer (let that any integer be' x') and '-1 ' will be -
if the integer is positive then the integer will be negetive

if the integer is negetive then the product will be positive

if the integer is 0 then the product will be 0
as any no. multiplied by 0 is 0
1 and three fourths is larger because it would be 1.35 as a decimal and the other would be 1.625
