Answer:
54.4
Step-by-step explanation:
3.4*16=54.4
Let the first brother = x
second brother = x + 2
third brother = x + 4
<span>The product of the first and third boys' ages is 20 more than twice the second boy's age:
x(x+4) = 2(x+2) + 20
x</span>² + 4x = 2x + 4 + 20
x² + 4x - 2x - 24 = 0
x² + 2x - 24 = 0
(x - 4)(x + 6) = 0
x = 4 or -6 (rejected, age cannot be negative)
First brother = 4
Second brother = 4 + 2 = 6
Third brother = 4 + 4 = 8
The three boys are 4, 6, and 8 years old.
Answer:
$2827.5
Step-by-step explanation:
Cost of each ticket = $32.50
The school choir bought 54 tickets for the Saturday concert and 33 tickets for the Sunday concert.
Cost for Saturday concert = 32.50 × 54
= $1755
Cost for sunday concert = 32.50 × 33
= $1072.5
Total cost = Cost for Saturday concert + Cost for Sunday concert
= $1755 + $1072.5
= $2827.5
Hence, he will pay $2827.5 in all for the tickets.
