What the answer? and what’s the work?

$13,475 was made during the first 2 hours

Step-by-step explanation:

1) find 20% of 350 and add it to 350 to find the # of ppl who purchased tickets in the 2nd hour

0.20*350= 70

350+70=420

420 people purchased tickets in hour 2

to find the total # of ppl who purchased tickets add 420 to 350

420+350=770

770 ppl purchased tickets in the first 2 hours

now multiply 770 with 17.50 to find the total money made

770*17.50=13,475

$13,475 was made during the first 2 hours

b. the decimal could be two-tenths.

step-by-step explanation:

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
