Price Elasticity of Demand

Salt and milk tea demand curves share one scale and both take a 20% hike; shaded areas show quantity change narrow vs wide, and brick-orange arrows mark the rise.

The 'Price Elasticity of Demand' economics lesson slide: two demand curves on same-scale axes with brick-orange annotations.
Start with this prompt

An economics principles lesson slide comparing salt and milk-tea demand curves on the same axes: after a price hike, the quantity change is narrow for one and wide for the other.

Arrows in dark indigo

Change the emphasis arrows and translucent areas from brick orange to dark indigo; the other colors stay.

Design it
Make a 4:3 landscape economics principles slide titled 'Price Elasticity of Demand: Same Price Hike, Why Do Sales Volumes Differ?'. Compare two demand curves on the same axes: table salt stands for a low-elasticity necessity, milk tea for a high-elasticity substitutable good; both rise 20% in price, and shaded areas show the quantity change is narrow for one and wide for the other.

Warm white background with charcoal-black title, axes, and demand curves; the price-rise range and the quantity difference are emphasized with brick-orange arrows and translucent areas, with guide lines toned down. Both charts keep the same scale and baseline, the bottom carries just one line of judgment method, and nothing is split into cards, so it reads like an economics diagram actually used for teaching.
Hike set to 30%

Raise the price increase on both sides from 20% to 30%; the comparison logic stays.
