Gamal spent $12.50 at the book store. The difference between the amount he spent at the video game store and the amount he spent at the book store was $17. The equation d minus 12.50 = 17 can be used to represent this situation, where d is the amount Gamal spent at the video game store. Which equation is an equivalent equation that can be used to find the amount Gamal spent at the video game store?
d = 17 minus 12.50
d = 17 + 12.50
d minus 12.50 = negative 17
d + 12.50 = 17

Answer:

29.50

Step-by-step explanation:

d-12.50=17

d=17+12.50

d=29.50

if d minus 12.50 = 17

then you transfer the number to the right side, beside the 17 then change the -12.50 to +12.50 because when the number is transfer to the different side you will also change the (-)(+) sign. and leave the d on the left side to solve the equation
