Arie has 46$ in his account and is saving 8.50 each week Olga has 14$ in her savings account and is saving 12.50 each week after how many weeks will arie and olga have the same amount in their accounts

After 8 weeks Arie and Olga will have the same amount in their accounts

Step-by-step explanation:

Assume that Arie and Olga will have the same amount in their accounts after w weeks

∵ Arie has $46 in his account

∵ He is saving $8.50 each week

∵ He will do that for w weeks

- To find his amount after w weeks add 46 to the product of

   w and 8.50

∴ Arie's amount = 8.50 w + 46

∵ Olga has $14 in her savings account

∵ She is saving $12.50 each week

∵ She will do that for w weeks

- To find her amount after w weeks add 14 to the product of

   w and 12.50

∴ Olga's amount = 12.50 w + 14

∵ They will have the same amount in w weeks

- Equate their amounts

∴ 12.50 w + 14 = 8.50 w + 46

- Subtract 14 from both sides

∴ 12.50 w = 8.50 w + 32

- Subtract 8.50 w from both sides

∴ 4 w = 32

- Divide both sides by 4

∴ w = 8

After 8 weeks Arie and Olga will have the same amount in their accounts

"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).
