<h3>What are word problems?</h3>
Word problems in mathematics are real-life situations that can be solved with the use of mathematical expressions (such as algebraic expressions) with the use of variables and their arithmetic operations.
Given that:
- Mona: (x)q + (y)d = 4.75 ----- (1)
- Gina: (y)q + (x)d = 4.00 ----- (2)
From equation (2), since the number of coins Mona has did not influence Gina's Coin;
The number of dimes Gina has is:
(x)d = 4.00 - (y)q
