Answer:

52

Step-by-step explanation:

9 - (-15) • 3 + 4 ÷ (-2)

9 - (-15) • 3 + 4 ÷ (-2)

9 + 15 • 3 + 4 ÷ (-2) = 9 + 15 • 3 + 4 ÷ -2

9 + 15 • 3 + 4 ÷ -2 = 9 + 45 + 4 ÷ -2

9 + 45 + 4 ÷ -2 = 9 + 45 + -2

9 + 45 + -2 = 9 + 45 + 2 (change the negative to positive)

9 + 45 - 2 = 54

54 - 2 = 52

final = original x multiplier^n

where 'n' is the number of years

Sub the values in

final = 700 x 1.055^7

final = 1018.27
