Stemson was charged $140 plus a pickup charge of $20 to ship 4 identical boxes by Fast Ship. The pickup charge applies regardless of how many boxes are picked up. What would have been the change to Stemson's account if he had shipped just 1 box?

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

answer: 1475
