You need 3 trucks of sand that hold 5 tons and 2 trucks that hold 3 tons to move all the sand in one trip
1) 32.75 times .40= 13.10
2) 32.75-13.10=19.65
The sale price is $19.65
First, find the 40% discount.
40% of 195 is 78
195 x 0.40 = 78
Subtract that from 195
195 - 78 = 117
Now, find 66 2/3% of 117, since it is an additional reduction after the original discount.
2/3 = 0.667, so 66 2/3% is 66.667%
117 x 0.66667 = 78.00039
And subtract that from 117
117 - 78.00039 = 38.99961, which in dollars would be $38.99. (hundredths, etc. of a cent are usually just dropped; no rounding involved.)
The discount price would then be $38.99
The top one shows they are parallel lines because it shows angles of both lines and the transversal
