Toshiro has $850 to invest. he can invest in a savings account that has an annual interest rate of 3.7%, and he can invest in a money market account that pays about 5.5% per year. write a polynomial to represent the amount of interest he will earn in 1 year if he invests x dollars in the savings account and the rest in the money market account.
a. 46.75-0.018x
b. 850 - 3.7x + 5.5y
c. 0.018x - 46.75
d. (3.7 + 5.5)x - 850

a. 46.75 - 0.018x

Step-by-step explanation:

He invest x dollars in the saving account and the rest in the money market account. It means that he invest x dollars in the saving account and (850-x) dollars in the money market account. Then, the amount of interest that he will earn in 1 year is:

I = 3.7%(x) + 5.5%(850-x)

Because, 3.7%(x) is the amount of interest earning by the saving account and 5.5%(850-x) is the amount of interest earning by the money market account. Therefore:

I = 3.7%(x) + 5.5%(850-x)

I = 0.037x + 0.055(850-x)

I = 0.037x + 46.75 - 0.055x

I = 46.75 - 0.018x

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

i believe b is the answer
