You need to use the compounding quarterly formula: A=P(1+r/n)nt
Where P is your starting amount, R is your interest rate, N is the number of compounds per year (4 compounds since it is quarterly) and T is time or amount of years.
A=50,000(1+0.4/4)4x7=28
A=50,000(1+0.1)28
A=50,000(1.01)28
A=50,000(1.32)
A=$66,064.55
