The price of a cellular telephone plan is based on peak and nonpeak service. Kelsey used 45 peak minutes and 50 nonpeak minutes and was charged $22.75. That same month, Mitch used 70 peak minutes and 30 nonpeak minutes and was charged $36. How much would 1 peak minute plus 1 nonpeak minute cost?

DID YOU FIND THE ANSWER I NEED IT TOO. someone help me please

i don't see any

step-by-step explanation:

an = 22 + (n-1) *6

110 seats

step-by-step explanation:

an=a1+(n-1)(d)

a1 = 22   this is the first item in the sequence

d =6   this is how the sequence goes up

a)   an = 22 + (n-1) *6

b) a12 = 22 + (12-1) *6

    a12 = 22+11*6

  a12 = 22 +88

  a12 = 110
