Question

Please help with 3 ASAP due TOMORROW

Answer 1

so, we know he submitted 3 already, and his teacher said that is 20%, let's say "x" is the 100%.


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 3&20\\ x&100 \end{array}\implies \cfrac{3}{x}=\cfrac{20}{100}\implies \cfrac{3\cdot 100}{20}=x`
