Answer:
<u>3 days</u>, <u>27</u>
Step-by-step explanation:
After 3 days :
- 3³ = 27 belts
- 4(3) + 15 = 12 + 15 = 27 belts
After 3 days, the number of belts and wallets sold will be the same, equal to 27.
=(5x+4)°
=(2x-2)°
=(4x-6)°
we know that,
=
+
According to the question,
so,
=(4x-6)°=(4×12-6)°=(48-6)°=42°
Answer: she needs to save $6510
Step-by-step explanation:
In the first year, she expects her total cost to be $9,850. Wei has already saved $1,220 for college. This means that the remaining amount that she needs would be
9850 - 1220 = $8630
she expects to receive grants and scholarships that total $2,120. Therefore, the amount of money that she should save to be able to pay for her first year of college would be 8630 - 2120 = $6510
