And (3×5)= 15
-1.331. -1.1 * -1.1 * -1.1
Simplify 3x × 2 to 6x
6x - x + 8y + 4x × 2 - 3x - 5y
Simplify 4x × 2 to 8x
6x - x + 8y + 8x - 3x - 5y
Simplify
<u>10x + 3y</u>
To find the sale price multiply the original cost by the sale percentage. (37x.2= 7.4) subtract this discount from the total (37-7.4= 29.6) this is your sale price. Now multiply this by the other percentage (29.6x.15= 4.44) (29.6-4.44= 25.16) $25.16 is your final answer
In expanded form, it would be 9*10 + 5*1 + 4 * 0.1 + 1 * 0.01 + 7 * 0.001. Hope this helps!
