643-189=450 bevause when you subtract you get 454 and if you are estimating you are rounding and it has a digit 4 in the ones place so you would have to round down because it is not 5 or more

Estimate 189 to the nearest tenth which would be 190. And then do the same for 643 which would be 640. 640-190= 450

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.
