A 16-oz jar of spaghetti sauce cost $3.59. if the cost per ounce is the same, how much would a 40-oz jar cost?

mario62 [17]

Answer:

B.$8.98

Step-by-step explanation:

We need to determine the cost per ounce. We divide the cost by the number of ounces

3.59/16 =.224375 per ounce

Take the price per ounce and multiply by the number of ounces to determine the price of the 40 ounce jar

.224375 * 40 =8.975

Rounding to the nearest cent

8.98 for a 40 ounce jar

Rina is 6x + 3:8 feet tall and Ryan is 5x + 1/8 feet tall. How much taller is Rina than Ryan?

Dimas [21]

Answer: Rina is $x+\dfrac{1}{4}$ feet taller than Ryan.

Step-by-step explanation:

Given, the height of Rina = $6x+\dfrac{3}{8}$ feet

The height of Ryan = $5x+\dfrac{1}{8}$ feet

To find : How much taller is Rina than Ryan?

Clue : Rina is taller than Ryan.

For that , we need to check the difference of the height between Ryan and Rina

i.e. (height of Rina) - (height of Ryan)

$=6x+\dfrac{3}{8}-(5x+\dfrac{1}{8})\\\\=6x+\dfrac{3}{8}-5x-\dfrac{1}{8}\\\\=x+\dfrac{3-1}{8}\\\\=x+\dfrac{2}{8}\\\\=x+\dfrac{1}{4}$

Hence, Rina is $x+\dfrac{1}{4}$ feet taller than Ryan.
