8. David is having a Super Bowl party and he needs
bottled water. Which of the following purchases will give
him the lowest unit cost?
a) $1.80 for a 6 pack
b) $6.00 for a 24 pack
c) $4.80 for a 12 pack
d) $10.00 for a 36 pack

Answer:

Work backward.  If at the end they both had 12 cents.  Then Betty had to have given Ann 6 cents.  Which means that Betty had to have had 18 cents, because there is always a total of 24 cents.  Which meant that before that, Betty had 9 and was given 9 cents.  So Betty originally had 9 cents.  So Ann had 24 minus 9 or 15 cents at the beginning.

Answer:

The amount is 5,955.08

Step-by-step explanation:

Here, we want to calculate compound interest

We can find this by using the compound interest formula

A = P( 1 + r/n)^nt

A is amount

P

is the principal = 5,000

r is the interest rate = 6% = 6/100 = 0.06

n is the number of times per year in which the interest is compounded = 1

t is the number of years = 3

Substituting these values;

A = 5,000(1 + 0.06/1)^3(1)

A = 5000(1.06)^3

A = 5,955.08

Answer:

3 3/4 inches = 562.5 miles

Step-by-step explanation:

Given that,

1/2 inch = 75 miles

It means,

1 inch = (75×2) miles

= 150 miles

3 3/4 inches= 15/4 inches

So,

[tex]\dfrac{15}{4}\ \text{inches}=\dfrac{15}{4}\times 150\\\\=562.5\ \text{miles}[/tex]

Hence, 3 3/4 inches is equal to 562.5 miles.

Answer:

38/3 yards

Step-by-step explanation:

Given that,

Fabric required to make a shirt = 2/3 of a yard

Fabric required to make a skirt = 12 yards

Answer:

the correct answer is 6..... option b

Answer:

6 days

Step-by-step explanation:

Given

[tex]Rate = -1\frac{1}{2}^\circ F[/tex] -- Negative because it decreases

[tex]Final\ Temperature = -9^\circ F[/tex] -- Negative because it still decreases

Required

Determine the number of days

Let the number of days be d.

So:

[tex]Rate * d = Final[/tex]

[tex]-1\frac{1}{2} * d = -9[/tex]

[tex]1\frac{1}{2} * d = 9[/tex]

Convert to improper fraction

[tex]\frac{3}{2} * d = 9[/tex]

Make d the subject

[tex]d = \frac{9 * 2}{3}[/tex]

[tex]d = 3 * 2\\\\d = 6[/tex]
