(8) 3.1 The learners sell 340 vetkoek for 15 weeks. They charge R12.00 for each vetkoek.
Calculate the profit they will make if the cost for each vetkoek is R4.00 and the
costs of all ingredients is R623.48 per week. ​

the answer is somewhere there guys it really . there im just not gonna answer

step-by-step explanation:

but i'm guessing ur first option tho

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
