Answer:
24 grams
Step-by-step explanation:
25% increase means 125% of the previous
125% : 30 grams
100% : X
125/100 = 30/X
X = 30 × 100/125
X = 24 grams
Answer:

-7a^2 b^3
Answer:
See below
Step-by-step explanation:
q = quarters value = .25 q
n = nickels = 4q value = .05 (4q)
summed = 12.60
<u>.25q + .05(4q) = 12.60 </u> <====== <u>can be used to solve the problem</u>
.45q = 12.60
<u>q = 28 quarters then nickels = 4q = 112 </u>
