Answer:
Total charge= [tex]\pounds 23.40[/tex]
Step-by-step explanation:
The basic plan of Jo's mobile phone costs [tex]\pounds 16[/tex] which includes
150 free minutes and 13p for each additional minute
150 free texts and 15p for each text
Since Jo made 170 minutes of calls, she exceeded the free minutes and had to pay
170 - 150 = 20 additional minutes, worth 13*20/100= [tex]\pounds 2.60[/tex]
She also sent 182 texts, 182 - 150 = 32 in excess, worth [tex]\pounds 15*32/100 = \pounds 4.80[/tex]
So the total charge for the month was [tex]\pounds 16 + \pounds 2.60 + \pounds 4.80 = \pounds 23.40[/tex]
Total charge= [tex]\pounds 23.40[/tex]
