Abby is making tie-dyed shirts. each shirt costs $3.95 and the dye for each shirt costs $0.50. she also needs to buy boxes of salt for $9.00. if she has $124.70 to start with, then how many tie-dyed shirts can she make?

the number of tie-dyed shirts that she can make is 26

Step-by-step explanation:

Let x represent the number of tie-dyed shirts that she can make.

Each shirt costs $3.95. This means that the total cost for x shirts would be 3.95 × x = $3.95x

the dye for each shirt costs $0.50. This means that the total cost of dye needy for x shirts would be

0.5 × x = $0.5x

She also needs to buy boxes of salt for $9.00. Therefore, total cost for making x tie-dyed shirts would be

3.95x + 0.5x + 9 = 4.45x + 9

If she has $124.70 to start with, then the number of tie-dyed shirts that she can make would be

4.45x + 9 = 124.70

4.45x = 124.70 - 9 = 115.7

x = 115.7/4.45 = 26

step-by-step explanation:

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
