Answer:
- 104 boxes
- 109 boxes
- 218 boxes
Step-by-step explanation:
Let b represent the number of boxes of cookies sold the first week. Then b+5 boxes were sold the second week, and 2(b+5) boxes were sold the third week. The total sold was ...
b +(b+5) +2(b+5) = 431
4b +15 = 431 . . . . . . simplify
b = (431 -15)/4 = 104 . . . . . subtract 15, divide by the coefficient of b
First week: b = 104
Second week: b+5 = 109
Third week: 2(b+5) = 218
<span>7x + 16 < -20 + 25x multiply the right-hand side by 5
16 < -20 + 18x combine like terms on right hand side: 25x - 7x = 18x
36 < 18x combine like terms on left hand side: 16 + 20 = 36
2 divide by 18: 36/18 = 2</span>
