a merchant is selling wind chimes from a booth at a flea market. he rents his space for $125 per day. the profit from each wind

Oksi-84 [34.3K]

Rents his place for $125 per day and his goal has to be in 5 days. Lets use 125 times 5 days then each chime sold is $12 and we need the number of chimes sold so we use "x" as our variable. Equation 125(5) + 12x = 3500. Hope this helps.

You invest $1500 in a bank account that has a 3% annual interest rate, compounded continuously. How much will you have in 15 yea

Mandarinka [93]

We use the formula:
Total = Principal * e ^ (rate * years)
Total = 1,500 * e ^ (.03 * 15)
Total = 1,500 * e ^ .45
Total = 1,500 * 1.5683121854 
Total = 2,352.47
