(2x +y)(5x-y+3)

10x^2 - 2xy + 6x + 5xy - y^2 + 3y

10x^2 -2xy+5xy + 6x - y^2 + 3y
 
10x^2 +3xy + 6x -y^2 +3y        

Looking at the answer boxes the sign looks wrong to me from y^2 ( a negative times a positive is a negative) I may be wrong. 

Anyone else?

Sholpan [36]

Answer:

Yearly budget= $3840

Monthly budget= $320

Step-by-step explanation:

His budget will be calculated first by rounding off to the nearest$10 all his monthly spending.

For groceries= $176.47

Round off=$ 180.00

For phone =$ 78.66

Round off = $80.00

For gas = $62.37

Round off= $60.00

His total round off = $180+$80+$60

His total round off = $320

Before the round off, his total spending was $176.47+$78.66+$62.37

= $317.5

So his monthly budget should be $320

And yearly budget =$ 320*12

Yearly budget= $3840
