Answer: Calvin has 13 quarters.
Step-by-step explanation:
Let Calvin have x quarters.
therefore amount of Calvin = 0.25 x [ 1 quarter = $0.25 ]
Number of dimes for Sara = x
[ Given that number of dimes of Sara = number of quarters of Calvin
Amount of dimes for Sasha = 0.1x [ 1 dime = $0.1 ]
Amount of Sasha without dime = $1.95 [ given]
total amount of Sasha = 1.95 =+ 0.1x
Since amount of Calvin and Sasha is same therefore
0.25x = 1.95 +0.1x
0.25x -0.1x = 1.95
0.15x = 1.95
x = 
x = 13

The degree of an expression in more than one variable is the highest sum of the powers of the variables in the terms.
Expression:
An algebraic expression is a combination of constant and variables connected by the signs of fundamental operations.
ex: 2x+5
Degree of an expression:
The degree of an expression in one variable is the highest exponent of the variable in that expression.
Ex:
2x^6 + x^4 + 5
Highest exponent = 6
so degree = 6
The degree of an expression in more than one variable is the highest sum of the powers of the variables.
Ex:
3x^1y^2 + 5x^3y^2 + 5
Sum of powers of variables = 3+2 = 5
Degree = 5.
