Answer:

The lowest is B) 5.50 for 5

Step-by-step explanation:

To find the lowest rate, divide the cost by how many times.

6.20/ 4 = 1.55 each

5.50/5 = 1.1 each

5.00/ 4 = 1.25 each

1.15/ 1 = 1.15 each

The lowest is B) 5.50 for 5

Answer:

28.8

Step-by-step explanation:

23+2x+3x+13=180 simplify the left side

5x+36=180 subtract 36 from both sides

5x=144 divide both sides by 5 to isolate the variable

x=28.8

A deposit of 4000 at 9.5% for 270 days

Lapatulllka [165]

The deposit is 4,000 so P = 4000.

The interest rate is 9.5%

9.5 ÷ 100 = 0.095.

r = 0.095: I = P*r*t*: I = P*r*tl = 4000*0.095*

(270/365)I = 281.095890410959 I = 281.10

So your answer would be: 281.10
