In canada, $1 and $2 bills have been replaced by coins. when marissa returned home to san fran from a trip to canada, she found that she had acquired 37 of these coins, with a total value of 51 canadian dollars. how many coins of each denomination did she have?

$1 coin is 23

$2 coin is 14

Step-by-step explanation:

We need to form mathematical equations that we can solve from this Long citation.

Firstly, let the numbers of $1 coins be a and that of $2 be b.

We know that there are 37 coins. Hence

a + b = 37

Now, total is 51 Canadian dollars.

a + 2b = 51

Let’s now solve this simultaneously

From 2 , a + b + b = 51

Let’s say this is 3. Now substitute 1 into 3.

37 + b = 51, b = 51 - 37 = 14

Since a + b = 37

a = 37 - 14 = 23

285=45x+60 because 285 stands alone and its you total. 45x is the its there with the variable x because the it says several
