Which explicit formula can be used to find the account's balance at the
beginning of year 5? What is the balance?
O A. A(n) = 700 + (0.003 · 700)(n-1); $719.45
O B. A(n) = 700 + (n − 1)(0.03 · 700); $784.00
O C. A(n) = 700 - (1 +0.03)(n − 1); $787.86
O D. A(n) = 700 - (1 + 0.03)"; $811.49

and that lightbulb changing party must be freaking lit!

answer: 193

explanation:

200-7 = 193

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
