But what the equation answer??

Equation/Question:

Sarah began the week with $2.60 in her lunch account. She deposited $20 on Monday, and then spent $4.75 each day that week for lunch. What was the balance in her lunch account at the end of the day on Friday?

Answer/Way I did it:

2.60+20.00 = 22.6

4.75 * 5 = 23.75 (There's obviously 5 school days)

22.60 - 23.75 = 1.15

(Simplify)

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8
