Question 1036476
total cost is {{{25(50)=highlight(1250)}}}
total amount received is {{{22(63)=highlight(1386)}}}
returns cost him $55 but gets refunded $50 for each calculator so in essence it only cost him $10 to return the two calculators. so {{{10+1250=highlight(1260)}}}
now subtract total cost from amount received
{{{1386-1260=highlight_green(126)}}}
