How much simple interest is earned on $4,000 in 3 1/2 years at an interest rate of 5.2%?
AveGali [126]

Answer:

$728

Step-by-step explanation:

The formula for simple interest is I = PRT, where I = interest earned/paid, P = principal amount deposited or borrowed, R = rate of interest as a decimal, and T = time in years.

I = PRT

I = (4000)(0.052)(3.5)

I = 728

Answer:

The skeletal system has many functions. Besides giving us our human shape and features, it:

Allows movement: Your skeleton supports your body weight to help you stand and move. Joints, connective tissue and muscles work together to make your body parts mobile.

Produces blood cells: Bones contain bone marrow. Red and white blood cells are produced in the bone marrow.

Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.

Stores minerals: Bones hold your body’s supply of minerals like calcium and vitamin D.

Jamie ordered 24 combo meals for $5 each for a party. The service charge for home delivery for the whole purchase was $6.
My name is Ann [436]
24 * 5 = 120
120 + 6 = 126 - total cost - meals and service

6/126 *100% = 4,76%

service charge was 4,76% of total costs.
