Answer:
The constant of proportionality is $1.80
y = 1.80x
Step-by-step explanation:
The constant of proportionality is $1.80
An equation that relates the total cost, y, and the number of lemons, x, is
y = 1.80x
where,
y =Total cost
x = number of lemon
When x = 4
y = 1.80x
= 1.80(4)
= 7.2
y = $7.2
When y = $4.20
y = 1.80x
4.20 = 1.80x
x = 4.20 / 1.80
= 2 1/3
x = 2 1/3
When y = $9.00
y = 1.80x
9.00 = 1.80x
x = 9.00 / 1.80
= 5
x = 5
When x = 18
y = 1.80x
= 1.80 × 18
= 32.4
y = $32.4
