A . subtract 1.33 from the first choice = 74.24 x 1.76= 130.486 No we need bigger!(I dont worry about decimal places the answer will just jump out of the numbers)
B. next 74.79 x 1.76 = 131.63 bigger still pretty sure its the next one because the last one D too big at 78.28.
C. 76.90 -1.33 =75.57x 1.76= 133.003 bingo ! $1.33
Much faster because on average each question only gets 2 minutes time to spend on them
1.33 “is” 1.76 “percent” “of” x, the original price. Cross multiplying and solving for x gives you the original price, then add $1.33 to get the Friday price.

I did it this way to find the original price:
“Is over of equals percent over 100.”
Is = % 1.33 = 1.76
— — —— ——
Of 100 X 100
1.33 “is” 1.76 “percent” “of” x, the original price. Cross multiplying and solving for x gives you the original price, then add $1.33 to get the Friday price.
Uh oh. The formatting of the post doesn’t look like how I posted it with the fractions. 😳😕
Let the Friday price = x
1.76% of x = $1.33
(1.76/100)x=1.33
1.76x=133
x= 133/1.76
x= 75.57
faster way to do it is ashokgupta’s method then adding 1.33 to get the answer
