S = number of scientific calculators

"an order of 42 calculators."

42-S = number of graphing calculators.

"the store paid $9 for each scientific calculator... graphing calculators, cost the store $56 each"

Total cost

= $9*S + $56*(42-S)

Since the total cost is $1553, solve for S in

$1553 = $9*S + $56*(42-S)
