A shop recorded total sales of $2,000 on Monday. On Tuesday, its sales fell by 10%. On Wednesday, sales fell by another 20% compared with Tuesday. From Wednesday to Thursday, sales increased by an amount equal to 25% of Monday’s total sales.

What is the net change, in dollars, in total sales from Monday to Thursday?

60 is the net change.

Step-by-step explanation:

(1) Monday's $2,000 with a 10% decrease in sales would be $200. 2,000 - 200 = $1,800

(2) If sales further decreased by 20% on Wednesday, then it would be $360. 1,800 - 360 = $1,440

(3) If sales increased by 25% from Monday's original total number of sales (2,000) that will be a $500 add-on to $1,440. 1,440 + 500 = $1,940

(4) So now you just subtract the final number of sales to the original number of sales. $2000 - $1,940 = 60

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
