Answer:
SI = $810
Amount = $3,810
Step-by-step explanation:
Given that ,
- P = $ 3,000
- R = 5.4%
- T = 5 yrs .
We can use the formula of SI to find the interest as ,
=> SI = P × R × T / 100
=> SI = $ 3000 × 5.4 × 5 / 100
=> SI = $ 30 × 5.4 × 5
=> SI = $ 810 .
- If you want to know total amount , then ,
=> Amount = SI + P
=> Amount = $ 810 + $ 3,000
=> Amount = $ 3,810

Answer:
Weight of the solution = 250 grams
Step-by-step explanation:
1) Consider the weight of solution as x grams.
32 % solution = 80 grams salt
32% of x = 80
(32/100)*x = 80
Solving for x:
x = (80*100) / 32
x = 250 grams
Set up a proportion.
12 cupcakes/ 0.5 hrs= 144 cupcakes/ x hrs
12*12=144
0.5*12=6=x
Final answer: 6 hrs
