Question

hello, can you help me with "writing equations".?"Matt spent $6.50 on his lunch. This is $2.25 more then his friend Jackson spent on his lunch. How much did Jackson spent on his lunch? Let j =the cost of Jackson's lunch."

Answer 1

$\begin{gathered} 6.50=2.25+j \\ 6.50-2.25=2.25-2.25+j \\ 6.50-2.25=j \\ j=4.25 \\ \\ \text{ Then j=4.25} \end{gathered}$
