Answer:
It should be A 3 1/4
Step-by-step explanation:
Given the equation p = 3(s + 100)/4
Where,
p = profit made
s = sales
Solving for s from the given equation
p = 3(s + 100)/4
Multiply both sides by 4
4p = 3(s + 100)
4p = 3s + 300
Subtract 300 from both sides of the equation
4p – 300 = 3s
Same as, 3s = 4p – 300
s = (4p – 300)/3
OR, s = 4p/3 – 100
If any of these two is in the options, it’s the right answer.
Answer:
31. How many cubic cm of rice will Amy's box contain
32. Amy has a box, its 20cm wide, 20cm high and 25cm long
33. multiplication
34. volume = width x height x length → volume = (20cm) x (20cm) x (25cm)
35. 10,000
36. To find the volume of the open box
37. An open box, its 30cm wide, 25cm high and 60cm long
38. multiplication
34. volume = width x height x length → volume = (30cm) x (25cm) x (60cm)
40. 45,000
Step-by-step explanation:
33. and 38. multiplication because the formula to find the volume is
width x height x length
35. volume = (20cm) x (20cm) x (25cm) = (400cm) x (25cm) = 10000
40. volume = (30cm) x (25cm) x (60cm) = (750cm) x (60cm) = 45000
