Answer:

$8000

Step-by-step explanation:

The method for calculating simple interest (I) is

I = \frac{PRT}{100}

where P is the principal, R is interest rate, T is time in years

here I = 1120, R = 3.5, T = 4 and P is to be found, thus

1120 = \frac{P(3.5)(4)}{100} ( multiply both sides by 100 )

3.5 × 4 × P = 112000

14P = 112000 ( divide both sides by 14 )

P = \frac{112000}{14} = $8000

Round 538.060 to the nearest whole number
sasho [114]

Answer:

538

Step-by-step explanation:

if you round the hundreth place up, the tenth place would be 1. However, rounding that would give you 0 as it's less than 5. Therefore, all decimal places would become 0, and that only leaves 538.
