The average daily sales at a bookstore was(7.6k + 2.2) dollars over a 4-day promotion. find the total sales during the promotion.

The total sales during the promotion is $69.6

Step-by-step explanation:

we are given

The average daily sales at a bookstore was(7.6k + 2.2) dollars over a 4-day promotion

we have to find total sales during 4 days

so, we can integrate it to find total sales

now, we can solve it

now, we can plug bounds

and we get

So,

the total sales during the promotion is $69.6

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.
