Equivalent equations are equations that have the same value
The equation is given as:
[tex]25q + 10d + 5n + 60 = 187[/tex]
(a) Simplify the equation
We have:
[tex]25q + 10d + 5n + 60 = 187[/tex]
Subtract 60 from both sides of the equation
[tex]25q + 10d + 5n + 60 - 60= 187 - 60[/tex]
Evaluate the like terms
[tex]25q + 10d + 5n= 127[/tex]
Hence, the simplified equation is: [tex]25q + 10d + 5n= 127[/tex]
(b) Having exactly 60 pennies
To have exactly 60 pennies in $1.87, then the simplified equation in (a) above must be true
However, the equation [tex]25q + 10d + 5n= 127[/tex] is not true for whole values of q, d and n.
Hence, it is not possible to have exactly 60 pennies
