Question

Sam and her sister both open savings accounts. Each begins with a balance of zero dollars. For every 5 dollars that Sam saves her sister saves 2 in her account. If Sam saves 40 dollars how much did Sam's SISTER save? *

Answer 1

Sam's sister saved $16 after Sam saved $40, following the ratio of $2 for every $5 that Sam saves.

Step-by-step explanation:

If Sam saves $40, and for every $5 Sam saves her sister saves $2, we need to determine how much Sam's sister would have saved. To do this, we first calculate how many times 5 goes into 40, which is 8 times. Then, we multiply this number by 2 to find out Sam's sister's savings.

So, Sam's sister saves 8 times $2, which is:

8 * $2 = $16

Therefore, Sam's sister saved $16.

Sam saves $5 for every $40 saved by her sister. If Sam saves $40, her sister would have saved:

Solution:

Sam saves $5 for every $40 saved by her sister, so we can set up a proportion:

Sam's savings/Sister's savings = $40/$5 = 8

If Sam saves $40, her sister would have saved $5 x 8 = $<<40*2=80>>80.
