Answer:
x = - 3, y = - 1
Step-by-step explanation:
y = 7x + 20 -----> equation 1
4x - y = - 11
4x - ( 7x + 20 ) = - 11
4x - 7x - 20 = - 11
- 3x = - 11 + 20
- 3x = 9
x = 9 / - 3
x = - 3
Substitute x = - 3 in equation 1,
y = 7 ( - 3 ) + 20
= - 21 + 20
y = - 1
Hence,
x = - 3
y = - 1
Answer:
21.62% more
Step-by-step explanation:
20 mins * 3 = 60 mins (1 hour)
10 baskets * 3 = 30 baskets
3$ * 30 baskets = 90$
90$ - 74$ = 16$
74 / 100 - 0.74
90 / 0.74 = 121.62
So she makes 21.62% more with 3$ per basket.
