A 4 pound bag of oranges costs $3.92.A 40 pound case of oranges costs $39.20.Which equation below is correct for this proportional relationship for pounds (x) and cost (y)

Step-by-step explanation:

Given

Cost of 4 lb orange = $3.92

Cost of 40 lb orange = $39.20

Required

Determine the proportion

The proportion can be calculated susing:

Where k = proportion

Make k the subject:

When y = 3.92 and x = 4

The proportion (k) is calculated as thus:

When y = 39.2 and x = 40

Using the same formula:

Substitute 0.98 for k in

Hence, the proportional relationship is

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral
