how much will it cost jaden to send 7 texts and talk for 12 minutes? if the equation is c=.15+.10

Question

 please help me 

 

Answer 1

I hope there must be variables  like

 

x = no.of text=7

 

y =minutes =12

 

c= total cost

 

I Assume from equation given by you

 

 cost for 1 text=0.10

 cost for 1 minute call=0.15

 

so equation is

c=0.15y+.10x

 

c=0.15(12)+0.10(7)

 

c=1.8 +0.7

 

c=2.5
