\frac{3}{15}-<u />\frac{d}{5}-(\frac{5}{6}+\frac{d}{3}=0

Step 1:<u />\frac{5}{6}+\frac{d}{3}=<u /><u />\frac{3}{15}- \frac{d}{5}- \frac{(2d+5)}{6}=0

Step 2:\frac{1}{5}- \frac{d}{5}= \frac{(1-d)}{5}- \frac{(2d+5)}{6}=0

Step 3:\frac{(1-d)*6-(2d+5)*5}{30}= \frac{-1*(16d+19)}{30}

Step 4:16d= -19:Divide \ both \ sides \ by \ 16:d= \frac{-19}{16}= -1.188

Your answer is <u />d\boxed{\boxed={ \frac{-19}{16}= -1.1888}}}}

3/15 -(d/5)=5/6+(d/3)
-(d/5)-(d/3)=5/6-3/15

-(8d/15)=19/30
-8d=19/2
-d=76
d=-76

a museum opened at 8:00 am. in the first hour 350 people purchased admission tickets. in the 2nd hour 20% more people purchased
Levart [38]

Okay, so we already know that 350 people purchased tickets in hour 1:

17.50(350 + ?) = ?

The question states that in the 2nd hour, there was 20% more people. So basically, we solve for 120% of the people from the 1st hour:

17.50(350 + 1.2(350)) = ?

Multiply 1.2 by 350:

17.50(350 + 420) = ?

Add:

17.50(770) = ?

Multiply:

17.50(770) = 13475

$13,475 was the total amount of money.
