Answer:
61 bags of lettuce
Step-by-step explanation:
Let's create two equations representing the cost of bags of lettuce:
Val's Veggies: 250 + 1.50x = V
Sally's Salads: 100 + 4.00x = S
If you buy 60 bags of lettuce from either store, the answers will be equivalent:
If x = 60
250 + 1.50x = V
250 + 90 = V
340 = V
100 + 4.00x = S
100 + 240 = S
340 = S
Now that both equations are equivalent, all we need to do to tip the balance and make Val's Veggies cheaper is purchase one more bag of lettuce:
x = 61
250 + 1.50x = V
250 + 91.50 = V
341.50 = V
100 + 4.00x = S
100 + 244 = S
344 = S
Since V represents the price of a bag of lettuce at Val's Veggies and V is now less than S (Sally's Salads), Val's Veggies is now the cheaper option.
Therefore, 61 bags of lettuce must be purchased in order for Val's Veggies to be the cheaper option.
Answer: Senior: $8, Child: 14
Step-by-step explanation:
3s + c = 38
3s + 2c = 52
c = 14
3s + 14 = 38
3s = 24
s = 8
Answer:
B) Brand 2
Step-by-step explanation:
Brand 1: $10.68 ÷ 12 = 0.89
Brand 2: $9.44 ÷ 16 = 0.59
Brand 3: $15.30 ÷ 18 = 0.85
Brand 4: $21.84 ÷ 24 = 0.91
Brand 5: $20.40 ÷ 30 = 0.68
Least cost per packet is of Brand 2
I got radius= 54
arc/2pi r = degrees/360
then fill in what you know: 24pi/2pi r = 80/360
Now cross multiply and you get: 8640pi = 160pi r
Now divide both sides by 160pi and you get: 54= r
Answer:
-21 - (-14) = <u>-21</u> + <u>14</u> = <u>-7</u>
Step-by-step explanation:
A - and a - make a +. So -21 - (-14) makes -21 + 14. Solve to get -7.
Hope it helps!
