Respuesta :
Marsha and Mark both sold 14 numbers of sweets each.
To understand more, check below explanation.
Equation in one variable:
Let us consider that Marsha and Mark both sold x number of sweets each.
Since Marsha sells her sweets for $0.25 each.
Amount Marsha earns = 0.25x
Mark sells his for $0.50 each.
Amount Mark earns = 0.50 x.
Given that, Marsha had $4.00 in her pocket in the morning, and Mark had $0.50.
4 + 0.25x = 0.50 + 0.50x
0.25x = 3.5
x = 3.5/0.25
x = 14
Hence, Marsha and Mark both sold 14 numbers of sweets each.
