The Everton college store paid $1859 for an order of 49 calculators. The store paid $11 each for scietific calculators. The others, all graphing calculators, cost the store $55 eaach. How many of each type of calculator ws ordered? Please answer in detail so that I can see what is wrong and where. thank you.

Let we have S scientific and G graphing
calculators. Then
S+G=49
11S+55G=1859
S=49G
11(49G)+55G=1859
S=49G
44G=1859539
G=30
S=19
