12 would be the y intercept because x is 0 and y is 12
Answer:
Step-by-step explanation:
1) P = £ 250
r =2%
t = 1
I = Prt
Interest = £ 5
2) P = £140
I = £ 4.20
t = 1
r =3 %
3) P = £ 4000
t = 3 years
I = £ 1440
r = 12%
4) Amount=p*[1+(r/100)]^t
= £323.76
Answer:
Step-by-step explanation:
- Total number of plants = 15
- Total cost = $96
- Cost of pink flowering plant = $8
- Cost of purple flowering plant = $5
<u>Let x and y be the number of plants bought. Then we have equations:</u>
- 8x + 5y = 96
- x + y = 15 ⇒ y = 15 - x
<u>Substituting y in the first equation:</u>
- 8x + 5y = 96
- 8x + 5(15 - x) = 96
- 8x + 75 - 5x = 96
- 3x = 96 - 75
- 3x = 21
- x = 7
Correct option is the second one
