The Everton college store paid $1668 for an order of 44 calculators. The store paid $8 for each scientific calculator. The others, all graphing calculators, cost the store $55 each. How many of each type of calculator was ordered?
Sorry! Actually, it was $8 the store paid, intead of $18. All else is correct. Thank you.
same way anyway
1668 = 8 x + 55 (44-x)
