Chitchat wireless charges $0.30 per minute plus a monthly base fee. in septembermaggieised 120 minutesand her bill was $51. write and solve and equiationto fing the cost if maggie used165 minutesin october

a). T=B+0.3x

b). Total wireless charges in October=$64.50

Step-by-step explanation:

a). The equation can be expressed as: T=B+0.3x

Where;

T=Total wireless charges

B=Monthly Base fee

x=number of minutes

0.3=rate per minute

Total wireless charges=Monthly Base fee+($0.30 per minute)

In September Maggie used;

120 minutes, Total wireless charges=$51

Monthly base fee=B

After substitution this can be expressed as;

51=B+(0.3×Number of minutes)

51=B+(0.3×120)

B+36=51

B=51-36=15

b). In October she used 165 minutes

Using equation T=B+0.3x

B=$15

x=165 minutes

T=15+(0.3×165)

T=15+49.5=64.50

Total wireless charges in October=$64.50
