Step-by-step explanation:
Answer:
f(x)=
1. 48x when x < or = 3,
2. 45x when 4 < or = x < or = 8
3. 42x when 9 < or = x < or = 19
4. 38x when x > 19
Step-by-step explanation:
3 boxes or less = Cost of tiles = $48
4 - 8 boxes ; cost = $45
9 - 19 boxes ; cost = $42
> 19 boxes ; cost = $38
Answer:
I think you mean divided by 5 so 629
Step-by-step explanation:
Answer:
34%
Step-by-step explanation:
To find the concentration of the new solution, take the percent time the amount of each of the solutions
40 ml* 25% + 60 ml * 40% = 100 ml* percent
40 * .25 + 60 *.40 = 100 * P
10 + 24 = 100 P
34 = 100 P
Divide each side by 100
34/100 = P
.34 = P
Changing to
34%
