Answer: There are 69 adults and 72 children went to the concert.
Step-by-step explanation:
Let x be the number of adults, and y be the number of children.
x + y = 141
3.5x + 2.5y = 421.5
x + y =141
x = 141 - y
3.5(141 - y) + 2.5y = 421.5
493.5 - 3.5y + 2.5y = 421.5
493.5 - y = 421.5
-y = -72
y = 72
x + y = 141
x + 72 = 141
x = 69

3^5×2^5=
243 × 32 = 7776

Answer:
$10,625.99
Step-by-step explanation:
The future value formula is useful for this.
FV = P(1 +r/n)^(nt)
where interest at rate r is compounded n times per year for t years. P represents the principal invested.
FV = $10,000(1 +.03/4)^(4·2) = $10000(1.0075^8) ≈ $10,625.99
The accumulated value will be $10,625.99.
