SCORPION-xisa [38]

Answer:

6 hours

Step-by-step explanation:

Let

x----> the number of hours worked at the donut shop

y----> the number of hours worked at the school bookstore

we know that

x+y=20

x=20-y -----> equation A

10.25x+8.75y=196 -----> equation B

Substitute equation A in equation B and solve for y

10.25(20-y)+8.75y=196

205-10.25y+8.75y=196

10.25y-8.75y=205-196

1.5y=9

y=6 hours at the school bookstore

Paisley has 8\tfrac{1}{4}8 4 1 cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 cup of yogurt. How

Ivenika [448]

Given:

Total Yogurt = $8\dfrac{1}{4}$ cups

Yogurt required for each smoothie = $\dfrac{11}{16}$ cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

$\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}$

Substituting the given values, we get

$\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}$

$\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}$

$\text{Number of smoothies}=3\times 4$

$\text{Number of smoothies}=12$

Therefore, the number of smoothies is 12.
