Hie, here's my question: $1800 at 6.5% for 30 months

miv72 [106K]

Answer:

A. 10105.86 (compound) or 3510 (simple)

B.11905.86 (compound) or 5310 (simple)

Step-by-step explanation:

If its's compound interest:

$1800(1 + \frac{6.5}{100}) ^{30} = 11905.86$

$11905.86 - 1800 = 10105.86$

If it's simple interest:

$6.5 \times 30 = 195$

$\frac{1800 \times 195}{100} = 3510$

$3510 + 1800 = 5310$

Four times a number plus five times the number is the same as ten more than eight

salantis [7]

Answer:

The number is 10.

Step-by-step explanation:

Given that:

Four times a number plus five times the number is the same as ten more than eight times the number.

Let,

x represent the number.

According to given statement,

4 times the number + 5 times the number = 10 + eight times the number

4x+5x=10+8x

Solving the equation,

9x=10+8x

Subtracting 8x from both sides

9x-8x=10+8x-8x

x=10

Hence,

The number is 10.
