Answer:
2 x + 6 . 8 = 8 x + I . 4
8x _2x = 6.8 - 1.4
6x = 5.4
X= 0.9
2x+ 6-8= 2×0.9 + 6.8 =8.6
A) 0.15 times $2,570 = $412.50
B) $122.85 times 2( 12 ) = $2,948.40
C) $2,570
D) All together it's $2,948.40 + $2,570 = $5,518.40
For D I didn't add the down payment because it's not an additional charge.
I only did the first one because I don't know if you want me to finish the rest.
Hope I helped :)
Something percent of a number must be smaller than the number.
And also, 39% of a number is equal to 39/100 multiplied by the number.
Thus:
39/100 * 1200
39/1 * 12
468
