Taylin buys 5 ounces of tea leaves for $2.35. At this rate, how much money does she need to buy 12 ounces of tea leaves? (second part) how would you work be different if you were asked how many ounces of tea leaves Taylin could buy with $10?

see below

Step-by-step explanation:

We can determine how much 12 ounces cost by using ratios

5 ounces       12 ounces

=

2.35                 x

Using cross products

5x = 12*2.35

5x = 28.2

Divide each side by 5

5x/5 = 28.2/5

x =5.64

If she has 10 dollars

5 ounces       y ounces

=

2.35                 10

5*10 = 2.35y

50 = 2.35y

Divide each side by 2.35

50/2.35 = 2.35y/2.35

21.27659574 =y

She can buy 21.3 ounces

$5.64; 21.3 ounces

Step-by-step explanation:

ounces : $

5 : 2.35

1 : X

X: the rate $ per ounce

1/5 = x/2.35

X = 0.47

a) 12 × 0.47 = 5.64

b) 0.47 = 10/n

n = 10/0.47

n = 21.2765957447
