Answer:

$9.00

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* 1.0\\\\\\x=(1.8)/(0.2)\\\\=9

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