Answer:

$9.00

Step-by-step explanation:

Given that $1.8 is 20% of the breakfast cost.

-We can use proportions to find the 100% cost of the breakfast before the tip.

-Let x be the full breakfast cost:

$0.2=1.8\\1.0=x\\\\0.2x=1.8\times 1.0\\\\\\x=\frac{1.8}{0.2}\\\\=9$

Hence, the full breakfast cost is $9.00 before the tip.

The amount of fish food, in grams required for the giant koi fish in the pond can be represented by the function $p(f)=\frac{f}{50} +7.5$ . If there are 50 fish, how many grams of fish food will you need?

$p(250)=\frac{250}{50} +7.5$
$p(250)=50 +7.5$
$p(250) = 57.5$
