1. A=2(w*l+h*l+h*w)
A=2(2*3)+2(4*3)+2(4*2)
A=2(6)+2(12)+2(8)
A=12+24+16
A=52

2.V=l*w*h
V=2*7/8*3/4
V=2*21/32
V=42/32. Divided both sides by 2
V=21/16
V=1 5/16

There are 195 adults and 320 children at a zoo. The zoo makes a total of $6,515 from the entrance fees, and the cost of an adult
Ostrovityanka [42]

Answer:

a+c=27

195a+320c=6515

Step-by-step explanation:

adult (a): 195

children (c): 320

total $: $6515

child $: 27

a+c=27 --> c=-a+27

195a+320c=6515

sub the first equation into the 2nd equation to get a=17

sub a=17 into c=-a+27 to get c=10

so, an adult ticket is $17 and a child ticket is $10.
