Answer:
Step-by-step explanation:
<u>We know that:</u>
- 12 ounce box of cereal = $3.84
<u>Work:</u>
- 12/3.84 ounce box of cereal = $1
- => 12/3.84 x 2.49 box of cereal = $2.49
- => 7.78 ounces (Rounded to nearest hundredth) = $2.49
Hence, 7.78 ounces cost $2.49.
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.
EQUATIONS:
24x + 32y = 264
x + y = 9
x is shirts, y is pants
SOLVING by substitution:
x = 9 - y
24(9 - y) + 32y = 264
216 - 24y + 32y = 264
8y = 48
y = 6
x + 6 = 9
x = 3
