Question

You have 8 times as many dimes as nickels. You have 18 dimes

Answer 1

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 :)
