Katie wants to purchase a camera that cost $149.99. she has $435.00 in her checking account. which statement is true if katie uses a debit card to pay for the camera? a. she will have to pay a penalty fee because she does not have enough money in her account b. she will have to make payments on the amount she borrows c. she will have to pay interest on the amount she borrows d. she will not have to pay a fee because she has enough money in her account

It’s D

Step-by-step explanation:

If the camera cost 149.99 and she has $435.00 in her account then she’ll have $285 left over

x =-.20752

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
