What is The simple interest earned on a deposit of $3000 at 6% for five years
Norma-Jean [14]

Answer: $900

Step-by-step explanation:

The simple interest is calculated using the formula:

(P × R × T)/100

where,

P = Principal = $3000

R = Rate = 6%

T = Time = 5 years

Simple Interest = (P × R × T)/100

= ($3000 × 6 × 5)/100

= 90000/100

= $900

Therefore, the simple interest is $900

Evaluate using the order of operations: 42 + 7 – 2.<br><br><br><br> HELP
Stels [109]

Answer:

47

Step-by-step explanation:

The order of operations is encoded in PEMDAS, or Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. Because there is only addition and subtraction, we just calculate it from left to right: 42 + 7 - 2 = 49 - 2 = 47.

Henry Devine bought a new dishwasher for $320. He paid $20 down and made 10 monthly payments of $34. What actual yearly interest
masha68 [24]
Henry paid a total of $360 for the dishwasher:  $20 + (10 x $34) = $20 + $340= $360

Therefore he paid $40 extra which we place over the original amount of the dishwasher:\frac{40}{320} =  \frac{4}{32} =  \frac{1}{8}

Dividing 1 by 8 we get  .125 which, when changed to a percentage becomes 12.5%
Henry paid a yearly interest rate of 12.5%
