Cookies are sold singly or in packages of 10 or 30. With this packaging, how many ways can you buy 60 cookies?
1 answer:
For easier, let's say x represents a pack of 10 and y represents a pack of 30
we can start with 2 of the 30's
2y=60
we can replace one of the 30's with 3 of the 10's
y+3x=60
and finally we can use all 10's
6x=60
there are only 3 ways

Answer:
4x − 30 = ≤12
Step-by-step explanation:
4x − 30 = ≤12
+30 on both sides
4x≤42
divided by 4 on both sides
x≤10.5
The answer is A! ———————-
50:40=x:35
5/4=x/35
times both sides by (4*35)
5*35=4x
175=4x
divide both sides by 4
43.75=x
costs $43.75
