Samantha cruz has 200 coins ( quarters and dimes) she has $44.00. Write a system of equations and determine how many quarters= ___ and dimes = she has.

she has 40 dimes and 160 quarters

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a quarter is 25 cents. Converting to dollars, it becomes

25/100 = $0.25

Let x represent the number of dimes that she has.

Let y represent the number of quarters that she has.

Samantha cruz has 200 coins ( quarters and dimes). This means that

x + y = 200

she has $44.00. This means that

0.1x + 0.25y = 44 - - - - - - - - - - - 1

Substituting x = 200 - y into equation 1, it becomes

0.1(200 - y) + 0.25y = 44

20 - 0.1y + 0.25y = 44

- 0.1y + 0.25y = 44 - 20

0.15y = 24

y = 24/0.15

y = 160

x = 200 - y = 200 - 160

x = 40
