Answer:
€2.24
Step-by-step explanation:
Let, the potatoes be x and apples be y
A/c to question,
4x = 3.80
x = 0.95
And,
3x + 2y = 7.33
3*0.95 + 2y = 7.33
2y = 7.33 - 2.85
y = 4.48/2
y = €2.24
Hence, the cost of 1 kg apple (y) = €2.24
Answer:
1. y=kx k is the constant of variation
2. y= 12x is in this form
3. with k= 12

Answer:
B. s = 0.85r
Step-by-step explanation:
The sale price is 15% off the regular price. In equation form, that is ...
s = r - 15%×r
