The answer should be $ 19.25. All you have to do is $7.70 * 2.5 which = $19.25
12 + 0.35X = 20.05
12 + 0.35X - 12 = 20.05 - 12
0.35X = 8.05
0.35X/0.35 = 8.05/0.35
X = 23
Hope this helps!!
The equation 150 thousand times 7 equals 1,050,000.
150,000*7= 1050000
Since addition is commutative, she can add anyway she wants.
