Answer: 70
Step-by-step explanation:10x70=700+300=1,000
72% can also be written as 0.72, so take 0.72 x 45 = 32.4
Subtract 32.4 from 45 45 - 32.4 = 12.6 You need 12.6 renewals in 5 days.
You would need 15/4 cups of brown sugar or 3 and 3/4 cups of brown sugar. Since 3/4 a cup is needed for one batch to make 5 batches you need 5 times the amount of brown sugar. To multiply 3/4 by 5 you can rewrite 5 as 5/1 and multiply the numerator of the fractions to get 15 and the denominator to get 4, so the answer is 15/4 which you can rewrite as 3 and 3/4.

To find B in terms of A (i hope this is what you want!) you can first multiply 3/7(B-25) by the reciprocal of 3/7, that being 7/3. You now have 7/3A=B-25, and through adding 25 on both sides, you have B=7/3A+25.
Hope this helps!
