{
// Declare Variables
int quarter, dimes, nickel, cent;
// Enter values for each
cout<<"Quarter: ";
cin>>quarter;
cout<<"Dimes: ";
cin>>dimes;
cout<<"Nickels: ";
cin>>nickel;
/*
In the United States, these coins have the following values

Answer:
70.15 cm³
Solution:
Data Given;
Mass = 55 g
Density = 0.784 g.cm⁻³
Required:
Volume = ?
Formula Used:
Density = Mass ÷ Volume
Solving for Volume,
Volume = Mass ÷ Density
Putting values,
Volume = 55 g ÷ 0.784 g.cm⁻³
Volume = 70.15 cm³
The rate of photosynthesis was measured by counting the amount of oxygen, a product of photosynthesis, generated by the plant. When the plant placed closer to the light source in a given time it generated more bubbles than when it was placed farther away from the light source.
