### Elona's Rate Growing Post

EEEYYYOO I'M RICOOO.
Part one

Definitions:

Rate-
measures two different quantities measures in the same unit.
Ratio- Compares two quantities measured in different units.

What is the difference between a ratio and rate?
A Rate is comparing two quantities measured in different units, and a Ratio compares 2 quantities in the same unit.

6. Gina earns \$78.00 for working 6 h. Asad makes \$192.50 after working 14 h. Determine each person's unit rate of pay. Who has a greater hourly rate of pay?

Gina: \$78/6h = 13/1h Gina gets \$13 an hour.
Asad gets more pay than Gina.

10. Trevor rode his mountain bike 84 km in 3 hours. Jillian rode her mountain bike 70 km in 2.5 hours. Who is the faster cyclist ?. How do you know ?

Trevor: 84/3 = 28km/hour.
Jillian: 70/2.5 = 28 km/hour.

So that means they were both going the same speed.

1. What would the recipe look like if it had to serve 10 people. Show your calulations.
Ground beef - 0.5 x 2.5 = 1.25 lb
Medium Onion diced - 1 x 2.5 = 2.5
Stalked celery finely diced - 1 x 2.5 = 2.5
Clove garlic minced - 1 x 2.5 = 2.5
Canned tomatoes chopped - 14 oz x 2.5 = 35 oz
Canned tomato paste - 0.5 x 2.5 = 1.25
Parsley - 1 x 2.5 = 2.5 tsp
Basil - 1.5 x 2.5 = 3.75 tsp
Oregano - 1 x 2.5 = 2.5 tsp
Sugar - 1 x 2.5 = 2.5 tsp
Worcestershire Sauce - o.5 x 2.5 = 1.25 tsp
Seasoning Salt - o.5 x 2.5 = 1.25 tsp
Bay leaf - 1 x 2.5 = 2.5

2. What would the recipe look like if it only had to serve 1 person. Show your work.

Ground beef - 1.25 ÷ 10 = 0.125 lb
Medium Onion diced - 2.5 ÷ 10 = 0.25
Stalked celery finely diced - 2.5 ÷ 10 = 0.25
Clove garlic minced - 2.5 ÷ 10 = 0.25
Canned tomatoes chopped - 35 oz ÷ 10 = 3.5 oz
Canned tomato paste - 1.25 ÷ 10 = 0.125
Parsley - 2.5 ÷ 10 = 0.25 tsp
Basil - 3.75 ÷ 10 = 0.375 tsp
Oregano - 2.5 ÷ 10 = 0.25 tsp
Sugar - 2.5 ÷ 10 = 0.25 tsp

Worcestershire Sauce - 1.25 ÷ 10 = 0.125 tsp
Seasoning Salt - 1.25 ÷ 10 = 0.125 tsp
Bay leaf - 2.5 ÷ 10 = 0.25

What I did is divide it all by 10 to get 1.
