Mark brought an electric tablet on sale for 1/4 off the original price of 825.00he also wanted to use a coupon for 1/5 off the sales price. how much did mark pay for the tablet

The sales price is 618.75. I get this by multiplying 825 by 1/4 then subtracting that number by 825, which equals 618.75. Then Mark uses the coupon for 1/5 of this price. 1/5 of 618.75 is 123.75. Subtract these two numbers to get 495. 495 is how much Mark pays for the tablet.

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
