Answer:

77.75%

Step-by-step explanation:

We just have to find the sums of the product of Joey's averages and their contribution to the total grade.

Test: 0.45 * 0.8 = 0.36 = 36%

Quizzes: 0.3 * 0.85 = 0.255 = 25.5%

Homework: 0.25 * 0.65 = 0.1625 = 16.25%

Total: 36% + 25.5% + 16.25% = 77.75%

During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% s

vodomira [7]

Answer:

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Investment of Sara during her 1st year of college = US$ 2,000

Duration of the investment = 4 years

Annual interest rate = 3%

2. Let's find the future value of this investment after 4 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment of Sara during her 1st year of college = US$ 2,000

number of periods (n) = 4

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 2,000 * (1 + 0.03) ⁴

FV = 2,000 * (1.03) ⁴

FV = 2,000 * 1.12550881

FV = 2,251.02

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.
