Answer:
A dress originally costs $120
Step-by-step explanation:
To find the original cost of the dress, we will follow the steps below;
let x represent the original cost of the dress
75% of x = $90
× x = $90
= $90
MULTIPLY both-side of the equation by 100
× 100 = $90×100
At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x
75x = $9000
DIVIDE both-side of the equation by 75
75x/75 = $9000/75
At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x
x= $9000/75
x = $120
A dress originally costs $120
Remember that scientific notation always contains a number between 0 and 10 that is multiplied by ten to some power. In this case, to get a number between 0 and 10 (7.2) we would move the decimal point once to the right. Since it is moving to ththe right, the exponent over the 10 will be negative, and it will be -1 because we moved the point once. So the answer is 7.2*10^-1
