Answer: Hello mate!
you put every number twice, I will consider that in this problem we have:
225 gallons of water initial with 5 pounds of sugar. then each minute you add 20 gallons of water and 4 pounds of sugar.
the concentration is defined as pounds of sugar divided by the gallons of water. The gallons of water are 225 initially and 20 per minute, this is written as 225 + 20tt, where t is the minutes. The pounds of sugar is 5 + 4 per minute, then this can be written as 5 + 4t
this is the equation that describes the concentration in pounder per gallon after t minutes.
147 =20x+47
147 is less than or equal to 20 multiplied by the number of hours she works (x) plus 47 the amount of money she already has
