Morgarella [4.7K]

Answer:

12 more days

Step-by-step explanation:

If Billy read 175 pages in 5 days, that means he read 35 pages a day.

175 / 5 = 35 pgs

If we continue this same pattern it will look like this:

595 - 175 = 420

420 / 35 = 12 days

mrs. li bought some crackers. she gave 30% of the crackers to her neighbor and ate 50% of the remaining crackers. mrs. li had 42

snow_tiger [21]

Answer:
She bought 120 crackers

Explanation:
Assume that the number of crackers she originally bought was x

We know that she gave her neighbor 30% of the crackers.\This means that:
amount left with her = x - 30%x
amount left with her = x - 0.3 x
amount left with her = 0.7x crackers

Now, we know that she ate 50% of that amount.
This means that:
she ate 50%(0.7x) = 0.5(0.7x) = 0.35x crackers
amount left with her = 0.7x - 0.35x = 0.35x crackers

Finally, we know that the number of crackers left with her is 42 crackers.
This means that:
0.35x = 42
x = $\frac{42}{0.35}$
x = 120 crackers

Hope this helps :)
