Question

Joan's income is $190 per week. She saves 20% of her weekly salary. How much does she save each week? [7] (2 Points ) Select the correct proportion (20)/(190)=(x)/(100) (190)/(x)=(20)/(100) (x)/(190)=(20)/(100) 7 Complete the sentence:

Answer 1

Joan saves $38 each week. Here is how we calculate this:

Step 1: We need to identify Joan's weekly salary, which is $190.

Step 2: We also know that she saves 20% of her salary. This 20% is expressed as a decimal when we are doing the calculation, therefore it becomes 0.20.

Step 3: To find out how much Joan saves every week, we calculate 20% of Joan's salary. In mathematical terms, we multiply her salary ($190) by the savings percentage (0.20).

Step 4: The multiplication of $190 by 0.20 gives us $38.

So, Joan saves $38 each week.

Looking at the provided proportions, the correct one is (20)/(100)=(x)/(190). In this proportion, '20' signifies the percentage of Joan's savings, '100' is the total percentage, 'x' is the unknown value we're trying to find out (which is the amount Joan saves), and '190' is the total salary. If we cross-multiply this proportion, we get the same result: $38.
