14.6%
Step-by-step explanation:
Total of the original prices:
$3.99 + $6.99 + $5.99 = $16.97
He paid $14.50 for the 3 shirts.
$16.97 - $14.50 = $2.47
He saved $2.47.
The percent he saved is
2.47/16.97 × 100% = 14.6%
Answer:
x = 24.52
Step-by-step explanation:
Since this is a right triangle, use Pythagorean Theorem to solve for the hypotenuse.
Pythagorean Theorem: a² + b² = c²
24² + 5² = x²
576 + 25 = x²
601 = x²
√601 = x
<span>Martin deposits $200
in a savings account that earns 5% annual interest.
year interest balance
1 200 * 5% 200(1.05)
2 200(1.05) * 5% 200(1.05)^2
3 200(1.05)^2*5% 200(1.05)^3
y 200(1.05)^y
=> m = 200 (1.05)^y
