P varies directly with Q and inversely with R, on the contrary, P varies inversely with R, this means P and R are indirectly proportional. In simple terms it means whatever you do to P, you do the opposite to R. O<span>r P=K*Q/R

</span>18=k*5/2 
<span>18=5k/2 </span>
<span>5k=36 </span>
<span>k=36/5 
</span>
P=K*Q/R

Answer:

The correct answer is d, there are infinitely many solutions.

saved Erica saved 20% on a shirt she just bought if the amount of money she saved was $6 what was the original price of the shir
olga2289 [7]
If the amount she saved was $6 for 20%, then the formula for finding savings would be cost*percentage.
But if you want to find the original cost, then you play with the current formula until you get this. $6/20%. Have a good one :)

You decide to enroll in a plan that gives you a 10% discount if you make telephone calls 7pm – 6am. The per minute charge is $0.
yanalaym [24]
<span>If you used the phone 130 minutes from 6 am to 7 pm, that would cost $13.00. 400 minutes from 7 pm to 6 am at a 10% discount would cost you $36.00. Add totals to get $49.00. Tax at 6% is 2.94. Your total bill would be $51.94.

Total bill = (0.10+0.06) x 130 + (0.10+0.06) x 400 x 0.90
              = $ 51.94</span>
