Sylvia deposits $50 into a savings account with a 2% interest rate. Using the formula for simple interest, how much will she have in the account in 5 years?

It's about 54.1324

You use the simple interest rate formula (that i learned)

A= (1+rt)

A is the final amount

P is the principal (original amount)

t is time

r is the interest rate

answer: this problem has only trivial solutions, with all points on the same line. x=5 or x=7/5.

step-by-step explanation:

there are three triangles, and three unknowns: x, y=length of middle segment, and z=cos(angles marked with red arc).

we need

and law of cosines,

the three equations are
