You have 8 times as many dimes as nickels. You have 18 dimes
fenix001 [56]

Answer:

$1.70

Step-by-step explanation:

Let the number of nickels be  x.

Thus, by the problem statement, the number of dimes is  [/tex] 8 \cdot x = 8x. [/tex]

Therefore, there are 8x + x = 9 coins in total. To find what x is, we need to solve the equation 9x = 18. This can be done by dividing both sides by 9 which gives x=2. Plugging these values in tells us that there are 2  nickels and 16 dimes. (Test it out!) Thus, the nickels are worth 2 \cdot 5 = 10 cents and the dimes are worth 16 \cdot 10 = 160 cents, so in all, you have 10 + 160 = 170 cents which is $1.70.

Hope this helps :)

Angelina_Jolie [31]
In 20 years a family will be able to earn 35 450 dollars. The interest that they earned is 5.5% compounded monthly. Now, let's find out how much will they need to save monthly to get this amount in 20 year:
=> 12 * 20 = 240 months
=> 35 450 / 240 months = 147.7 dollars per month is the money with interest
Let's subtract the interest
=> 147.7 * 0.055 = 8.1 dollars.
=> 147.7 - 8.1 = 139.6 dollars per month.
