Answer:x=18/5
Step-by-step explanation:
Using proportions, considering the amount she received from each person, it is found that Annie had 30 sweets originally.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, we have that:
- Initially, she had n sweets.
- With the ones she got from Teddy, the amount became 1.5n.
- With the amount from Rosie, the amount became 1.4 x 1.5 x n.
The final amount was of 63, hence:
1.4 x 1.5 x n = 63
n = 63/(1.4 x 1.5)
n = 30.
Annie had 30 sweets originally.
