Exact cost per ingredient in a recipe

30 Views Asked by At

Math unfortunately hasn't been my forte. I know this is fairly easy stuff but it needs to be precise. Please provide me with the answers. The steps would also be great.
Thanks

  1. If 3175.15g of salt cost $5, how much would 13g of salt cost?

  2. If 226g of pepper cost $4.20, how much would 1.8g cost?

  3. If 25G of spices cost $20, how much would 1g cost?

  4. If 994g of special sugar cost $17, how much would 1.3g cost?

  5. If 750ML of wine cost $15, how much would 35ml cost?

  6. If enough storage bags for 11339.8g cost me $22, how much would it cost for enough bag for 453.592g?

All of those are solved using the same principle. I will do the first one as an example, here I will use $=$ as an equivalence rather than absolute equality.

$$3175.15g=\$5$$ Divide both sides by $3175.15$ to get $$1g=\$\frac{5}{3175.15}$$ Now multiply both sides by $13$ to get $$13g = \$\frac{(5)(13)}{3175.15}=\$0.020471473$$

Now use the same principle for the others
