Question

help

Answer 1

5. For this question, you will need a parent/guardian or a friend. Have this individual grab a handful of coins making sure there are only two types of coins in the group (i.e., nickels and dimes, quarters and pennies, pennies and dimes, etc). Your parent/guardian or friend should tell you the type of coins they’ve chosen, how many coins they have and the dollar amount of the group. From this information, you will set up two sets of equations and determine how many of each coin they have in their hand. Please send your instructor the name of the individual who helped you with this question, your two equations and the work you did to solve the system.

Answer 2

X + Y = 10

X(10) + Y(5) = 75

---------------

there are the equations, then you solve from there by getting a value for either x or y

-------------------

y = -x+10

then substitute that into the other equation
-----------
X(10) + (-x + 10)(5) = 75

then you solve out into

10x - 5x= 75 - 50

that goes into 5x = 25

x = 5

then plug that into the other one
---------------------

y + 5 =10

y = 10 - 5

y = 5

-----------
so you have 5 dimes and 5 nickles!
