For A well I can't do a graph ,but to do it you would start at 50 going up 25 each week
For B it would be 300 because 25×10=250 plus the 50 from his grandmother he would have 300
Answer:1
Step-by-step explanation:
terms are separated by + or - signs
3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5
3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1
7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2
