<h3>Answer:</h3>
B) 10 pounds
<h3>Explanation:</h3>
Let x represent the amount of 70¢ candy to be added. The value of the mixture can be written as ...
... 90×30 + 70x = 85×(30+x) . . . . . where 30+x is the total weight of the mix
... 2700 +70x = 2550 +85x
... 150 = 15x . . . . . . add -70x-2550
... 10 = x . . . . . . . . . divide by the coefficient of x
10 pounds of candy at 70¢/lb must be added.
Answer:

Step-by-step explanation:
Sarah has $55
Her expenses are 3 shirts priced at $m each.
Total cost of 3 shirts at $m each would be the multiplication of each:
3 * m = 3m
The amount of money Sarah has left would be the total she had MINUS what she spent on 3 shirts. That would be:
Remaining Money = 55 - 3m
