Answer:
-2
Step-by-step explanation:
1800 - 1350= 450 3 months after the purchase he payed $450
450/3= $150 per month
1350 - 1050= 300 5 months AFTER THE PURCHASE he payed $300
300/2= $150 per month
^after 2 more months he payed $300^
$150 per months
Equation: (initial amount) - (150)M
M= amount of months after purchase
B = 1800 - 150M
2=log(3x+4)
y = loga b a^y = b
since this is base 10
10^2 =3x+4
100 = 3x+4
subtract 4 from each side
96 =3x
divide by 3
32=x
