Question

Jamie has 70 coins. They total $6.30. If they are only dimes and nickels find out how many of each she has.​

Answer 1

Jamie has 14 nickels and 56 dimes

Explanation:

Start by identifying labels for the # of dimes and nickles. Lets use x for nickels and y for dimes.

From here you can make two formulas (x + y = 70) and (5x + 10y = 630) when you put them into a graphing calculator they should intersect at (14,56) which means the x = 14 and y = 56
