Answer:
1. around 4.86 or 4.9 for the nearest tenth
2. 17 months
Explanation:
1. (1.7×10^6)/(3.5×10^5) = (1.7/3.5)×(10^6/10^5) = 0.4857×10 = 4.857
Therefore, 1.7×10^6 is about 4.857 times as great as 3.5×10^5.
2. start by finding out how much Erica still owes after the down payment:
Total cost - Down payment = $1,867 - $320 = $1,547
divide the amount still owed by the monthly payment to find out how many months Erica will be paying:
$1,547 ÷ $91 per month = 17 months (rounded up)
Therefore, Erica will be paying for the bike for 17 months
