Jean is working out the total cost for her new mobile phone plan with an 18 month contract. The provider charges an initial connection fee of $75. The plan costs $25 a month for the first six months, and then $35 a month for the remaining 12 months. How much will Wendy pay in total for her 18 month contract?

$35x 12= $420 so that's for the remaining 12 months. $420+ 75=$495. The next step is to multiply $25 and 6. $25x6= $150.

$495+$150= $645 per month.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
