Okay. To find the percent discount of the sale price, we can write and solve a proportion. You set up the proportion like this:
change/original = x/100
Change is the amount between both numbers and the original is the previous amount. In this case, we are solving for "x", which is the percent discount. 170 - 143.20 is 26.8. Now, let's plug in the values: 26.8/170 = x/100. Cross multiply the values diagonally to get 2,680 = 170x. Divide each side by 170 to isolate the "x". 2,680/170 is 15.76470588254 or 16% when rounded to the nearest whole number. x ≈ 16%. The percent discount is approx. 16%.
Answer:
B. 2
Step-by-step explanation:
We have been given that a worker carries jugs of liquid soap from a production line to a packing area, carrying 4 jugs per trip.
Since worker has made 17 trips, so total number of hugs of liquid soap would be 17 times number of jugs carried per trip.
.
Since each carton holds 7 jugs, so number of cartoons would be 
.
We can see that there are 9 completely filled cartoons and there are 5 jugs remaining, so we need 
jugs.
Therefore, we need 2 jugs to fill the 10th cartoon and option B is the correct choice.
Step 1: Subtract 3x from both sides.
−x+7=−52
Step 2: Subtract 7 from both sides.<span><span><span><span>
