Answer:
a. the order processing fee changed to $ 15 and each bottle charge changed to 115%
b. the equation of cost will be changed to : (1.2 x 1.15) b + 15 = 1.38b + 15
Step-by-step explanation:
a. the order processing fee changed to $ 15 and each bottle charge changed to 115%
b. the equation of cost will be changed to : (1.2 x 1.15) b + 15 = 1.38b + 15
* this equation limited to a single order with b bottles
-3/16 is the answer or -0.1875 in decimal form
Answer: One batch of Fried rice costs $3.55
Step-by-step explanation: One batch consists of 5 pounds. One pound is 71 cents. We have to multiply 71 by 5. The product of 71 and 5 is equal to 355 cents. One batch of Fried Rice costs 355 cents or $3.55
Answer:
- the largest number that cannot be made is 23
- see below for an explanation
Step-by-step explanation:
<em>Why numbers greater than 23 can be made</em>
From any number that Larry can make that includes an appropriate number of stamps, Larry can ...
- add 1 by adding 1×9 and taking away 2×4
- add 2 by adding 2×9 and taking away 4×4
- add 3 by adding 3×9 and taking away 6×4
- add 4 by adding 1×4
- add 5 by adding 4 and 1 (add 9, take away 4)
- add 6 by adding 4 and 2 (add 2×9, take away 3×4)
- add 7 by adding 4 and 3 (add 3×9, take away 5×4)
- add 8 by adding 2×4
- add 9 by adding 1×9
Clearly, for Larry to be able to continue adding any number, he must start with a number that contains at least 6×4 cents = 24 cents.
Larry can make 24 cents from 6 4-cent stamps. Using the above table, he can add any amount to that.
___
<em>Why 23 cannot be made</em>
For 23 cents, the number of stamps must include 0, 1, or 2 9-cent stamps, so there are 3 cases to try for making 23:
- 23 cannot be made from 0 9-cent stamps because 23 is not divisible by 4
- 23 cannot be made using 1 9-cent stamp, because 14 is not divisible by 4
- 23 cannot be made using 2 9-cent stamps, because 5 is not divisible by 4.
Therefore, 23 cannot be made.
