Caleb has a total of 130 coins, all of which either dimes or quarters. The total value of the coins is $26.50. Find the number of each coin. A. 20 dimes + 10 quarters = 130 B. 40 dimes + 90 quarters = 130 C. 70 dimes + 78 quarters = 130 B. 40 dimes + 90 quarters = 130 40*(.10)+90*(.25)= $26.50
Domo Sims has been pricing speed-pass train fares for a group trip to New York. Three Adults and four children must pay $124. Two adults and three children must pay $88.
