Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
What pattern are you talk about
3.25(4)+2(6) --plug in values
13+12 --multiply
$25 --answer
12 divided by 10 is 1.2. 15 multiplied by 1.2 is 18 so x equals 18
150 to 60. But the more commen why to do that were to simplify it.
