So total she saved 22+39 so far. That's 61 dollars in total (22+39=20+41=61).
She needs 100 dollars total, but she has 61 already, so she only needs 100-61=39 more: she needs 39 dollars more.
Answer:
D) 12.2
Step-by-step explanation:
EH is median
FH = HG
6x - 1.1 = 4x + 1.3
Add 1.1 to both sides
6x = 4x + 1.3 + 1.1
6x = 4x + 2.4
Subtract 4x from both sides
6x - 4x = 2.4
2x = 2.4
Divide both sides by 2
x = 2.4/2
x = 1.2
FH = 6x - 1.1
= 6*1.2 - 1.1
= 7.2 - 1.1
= 6.1
FG = 6.1 + 6.1 = 12.2
