Answer:
Brand A is more expensive by .02 per ounce
Step-by-step explanation:
To find the cost per ounce, take the cost and divide by the number of ounces
Brand A
1.28/8 =.16 per ounce
Brand B
1.68/12 = .14 per ounce
The difference is .16-.14 = .02 per ounce
Answer:
A: Store A will cost about $1.28 less
Step-by-step explanation:
Okay, let's find the unit rate of cost. To find that for store A, we divide 7.26 by 3, which gets us 2.42. For store B, we need to look for the first intersection. We find that at (20, 50). Let's divide 50 by 20. That gets us 2.50. Let's multiply 2.42 and 2.50 by 16. That gets us 38.72 for store A and 40 for store B. Let's subtract 38.72 from 40. That gets us 1.28. That means store A costs $1.28 less than store B. That makes our answer A.
Answer: x = - 4
Step-by-step explanation:
7-2x=1
PEMDAS
so add 7 to both sides
-2x=8
divide by -2 from both sides
x=-4
