Ravi purchased a prepaid phone card for $15.00. Calls cost 10 cents a minute using this card. The credit, C (in dollars), left on the card after it is used for x minutes of calls is given by the following function.
C(x) = 15.00 -0.10%
How much credit is left on the card after Ravi uses it for 30 minutes of calls?

Turn 40% to a decimal.

40%= .4

Multiply that by 35.

35*.4= 14

14 students in the class were girls.

I hope this helps!
