Step-by-step explanation:
- 47.00 - 36.50 = 10.50
- 10.50 / 3 = 3.50
- answer= $3.50
to make sure:
3.50 × 3 = 10.50
10.50 + 36.50 = $47
For Wyatt's recipe the rate is:
r1 = 3.15 / 9
r1 = 0.35
For Cora's recipe the rate is:
r2 = 2.4 / 8
r2 = 0.3
The difference between both recipes is:
r1-r2 = 0.35 - 0.3 = 0.05
Answer:
0.05 cups of flour per shortcake less is needed for Cora's recipe

Answer:
Hello!!!
In this specific case the constant of proportionality is s (speed).
Step-by-step explanation:
The constant of proportionality stay "constant" (as the name suggests) in a certain case.
meaning, the speed itself remains constant at any given distance or time.
You can use the constant of proportionality and either distance or time to find the missing varliable since it remains constant.
you can also switch up the formula:
d=st
t=d/s
s=d/t
i really hope this helps!!!!!
