Answer:

b=-20

Step-by-step explanation:

We will have to solve this question based on how the question is given

So let's solve the given question

2=7+b/4

To start by finding the LCM for the right side and the LCM is 4

2=28+b/4

Let's cross multiply

2×4=28+b

8=28+b

Let's make b the subject of formula by substrating 28 from both sides

-20=b

Therefore the final answer is b=-20

grigory [225]
We’ll first find how much she has left as her savings
$490-$396.90= $93.70

Now we’ll go for cross multiplication
100% $490
? $93.70

? = 100 x 93.7/490
? = 19.1 %

So the answer is 19.1% which rounded to the nearest whole number is 19%. The answer is the first option.
Hope it helped you
