Frank made roughly around $792 in total this week
(a)
![SI = \frac{PRT}{100} \\ = \frac{1800 \times 5 \times 1}{100} \\ = 18 \times 5 \\ = 90](https://tex.z-dn.net/?f=SI%20%3D%20%20%5Cfrac%7BPRT%7D%7B100%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1800%20%5Ctimes%205%20%5Ctimes%201%7D%7B100%7D%20%20%5C%5C%20%20%3D%2018%20%5Ctimes%205%20%5C%5C%20%20%3D%2090)
Total amount = SI + Amount
= 90 + 1800 = $1890
(b)
![SI = \frac{PRT}{100} \\ = \frac{2600 \times 12 \times 3}{100} \\ = 26 \times 12 \times 3 \\ = 26 \times 36 \\ = 936](https://tex.z-dn.net/?f=SI%20%3D%20%20%5Cfrac%7BPRT%7D%7B100%7D%20%20%5C%5C%20%20%3D%20%5Cfrac%7B2600%20%5Ctimes%2012%20%5Ctimes%203%7D%7B100%7D%20%20%5C%5C%20%20%3D%2026%20%5Ctimes%2012%20%5Ctimes%203%20%5C%5C%20%20%3D%2026%20%5Ctimes%2036%20%5C%5C%20%20%3D%20936)
Total amount = SI + Amount
= 936 + 2600 = $ 3236
(c)
![SI = \frac{PRT}{100} \\ = \frac{3125 \times 15 \times 0.2}{100} \\ = 93.75](https://tex.z-dn.net/?f=SI%20%20%3D%20%20%5Cfrac%7BPRT%7D%7B100%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B3125%20%5Ctimes%2015%20%5Ctimes%200.2%7D%7B100%7D%20%20%5C%5C%20%20%3D%2093.75)
Total amount = SI + Amount
= 93.75 + 3125 = $ 3,218.75
Answer:its 22% pls just give me brainliest so i can move up a ranking
Step-by-step explanation:
Answer:
I think the answer is option 2
Answer:
x = 40 1/2
Step-by-step explanation:
The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the larger one. Then x is half the length of the corresponding segment marked 81.
x = 81/2
x = 40 1/2
___
You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.
