They sell 103 tickets at $18.99 per ticket, 321 tickets at $21.50 per ticket and 48 tickets at $27.99 per ticket. Estimate the total amount of money obtained.

Question

This is for math and we need to round and estimate the total amount of money obtained

 

Answer 1

Cat, since we are estimating, we'll round first.

 

$18.99 is close to $19.103 is close to 100. To multiply by 100, move the decimal right two places. $1900

 

321 is close to 320. $21.50 is close to $20. To multiply by 20, move the decimal to the right one and double. $6400. Add another dollar and a half for 320 tix ($320 + $160 = $480).

 

48 is close to 50 and $28.99 is close to $29, or even $30. 50 x $30 = $1500.

 

$1900 + $6400 + $1500 + $480 = $10280. Of course, the actual sales are only near this amount.

Answer 2

total money obtained should be

 

103 * 18.99 + 321 * 21.50 + 48 * 27.99 = 10200.99  

 

round the number, we get $10201
