Answer:
y=2500(0.85)^d
Step-by-step explanation:
Seeing as there are no option choices, I shall digress.
Because of a decrease of 15% each day, it means exponential decay. Using the formula y=a(1-r)^x, we have y=2500(1-0.15)^d -> y=2500(0.85)^d
Your function would thus be y=2500(0.85)^d
Since there was five boxes of crayons and there was 3 crayons in each one, the would be 15 in total. (crayons) And there was three people, 15/3=5 crayons per person.
Equation: 3x=15
x stands for the amount of crayons each person gets.
.0018529956763434 is my calculated answer.<span />
Answer:
Step-by-step explanation:
Let's look at some other ratios that equal 8:6 We could increase them or decrease them. For instance if we cut one in half we cut the other one in half, so 8:6 would be the same ratio as 4:3. With the same thinking if we double one we double the other so 8:6 s the same ratio as 16:12. Now, we want to go from 8 to 28. What do we multiply 8 by to get to it? Or, it might be easier to use 4:3 and see what you multiply 4 by. Then you multiply 3 by that same number to get the other number.
Let me know if that doesn't make sense.
