Final answer:
Using the information provided, Breanna has 2 quarters, 4 nickels, and 7 dimes, which totals $1.40 in her purse.
Step-by-step explanation:
Calculating the Total Amount of Money
Breanna has quarters, dimes, and nickels in her purse. To begin calculating the total amount of money Breanna has, let's use the information given in the question. We know that she has 2 quarters. Since there are 2 more nickels than quarters, that means Breanna has 2 + 2 = 4 nickels. Since there are 3 fewer nickels than dimes, Breanna must have 4 + 3 = 7 dimes.
Now, let's convert the number of each type of coin into its monetary value. Breanna has:
2 quarters, which is 2 x 25 cents = 50 cents
7 dimes, which is 7 x 10 cents = 70 cents
4 nickels, which is 4 x 5 cents = 20 cents
Adding these amounts gives us the total sum of money that Breanna has:
50 cents (quarters) + 70 cents (dimes) + 20 cents (nickels) = 140 cents or $1.40.
Therefore, Breanna has a total of $1.40 in her purse.
