The required cost is $ 101.22.
This problem can be solved by unitary method.
Given that monthly cost of customer if he uses 410 minutes is $71.
So, cost per minute =
=$ 0.17
And if the customer uses 720 minutes then the cost is $118.
So, cost per minute is =
=0.16
Now if he uses 687 minutes then for 410 minutes cost incurred will be
= 410 × 0.17
= $ 69.7
And for next 197 minutes cost incurred will be = 197 × 0.16
= $ 31.52
Total cost for 687 minutes = $(69.7 + 31.52)
= $ 101.22

Slope intercept: y = mx + b
2x = 2y - 10
2y = 2x + 10
Divide by 2
Y = x + 5
Answer:
The combined weight of red and green grapes in total= 7.625 pounds.
Step-by-step explanation:
The amount of red grapes purchased = 3.5 pounds
The amount of green grapes purchased = 4 pounds and 2 ounces
Now, 1 ounce = 0.0625 pounds
So, 2 ounces = 2 x 0.0625 p = 0.125 pound
So, the amount of green grapes purchased = 4 pounds + 0.125 pounds
= 4. 125 pounds
Now, the combined weight of grapes = weight of ( red + green) grapes
= 3.5 pounds + 4. 125 pounds
=7.625 pounds
Hence, the combined weight of the red and green grapes she bought in total is 7.625 pounds.
