Ravonda purchased a ring costing $30,000 by taking out a 5.5% add-on installment loan. The loan requires a 25% down payment and equally monthly payments for 4 years. How much are her monthly payments?

She has to pay $503.125 monthly till 4 years

Step-by-step explanation:

Cost of the ring = $30000

Add on = 5.5% of the cost of the ring

=( 5.5 x 30000) /100

= $1650

Down payment = 25% of the cost

= (25 x 30000) /100

= $7500

Time = 4 years

Loan amount = 30000 - 7500

=$ 22500

Total amount to pay = 22500 + 1650

= $24150

Monthly instalment= 24150/(4 x 12)

=  $503.125

She has to pay $503.125 per month till 4 years.

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

step-by-step explanation:

you can't solve x because it is 2 linear equation and you only have one equation
