9514 1404 393

  a. 38

  b. 95

  c. 57

Step-by-step explanation:

In this context, you can consider "of" to mean "times." It can also be helpful to think of % as meaning /100.

a.  p = 20% × 190

  p = 20/100 × 190 = 38 . . . . you have 38 pennies

__

b. 190 = 200% × r

  190 = 200/100 × r . . . . replace % with /100

  190 = 2 × r . . . . . . . . . simplify the fraction

  190/2 = r = 95 . . . . you have 95 rare coins

__

c. n = 60% × r

  n = 60/100 × 95 = 57 . . . . you have 57 nickels

c.
