Q: Is Kramizo really free for CXC Economics students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Economics questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Economics syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A rum distillery in Barbados finds that when it increases production from 1,000 to 1,500 bottles per week, total cost rises from $15,000 to $19,000. What is the marginal cost per bottle for this increase in output?

Accepted Answer

$8.00 — 00. Award 1 mark for correct calculation: MC = Change in TC ÷ Change in output = ($19,000 - $15,000) ÷ (1,500 - 1,000) = $4,000 ÷ 500 = $8.00. A is incorrect — this confuses the calculation. C is incorrect — this is average cost at new output. D is incorrect — this is average cost at original output.
