Shopping: Tax Situation: You are purchasing four items and want to calculate the tax. The items cost $2.50, $8.75, $3.00, and $10.25. The tax rate is 6%. How much is the tax?
Calculation With Distribution. PLS show all work step by step

The tax is normally done to the total so add the prices up  2.50+8.75+3.00+10.25=24.5

percent is 6%

percent means parts out of 100 so

6%=6/100=0.6/10=0.06/1=0.06* 6% of total* 'of'' translates to multiply

24.50 times 0.06=tax=1.47

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

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
