3. the amount of money on the gift card when Salim receives it
Let m be the amount of money on the gift card in dollars when Salim receives it
Which equations can you solve to find the value of m? Choose ALL that apply
1, m-7.50=12.50
2, m+7.50=12.50
3, 12.50m=7.50
4, m=7.50+12.50
5, m+12.50(7.50)
1. m-7.50=12.50
4. m=7.50+12.50
What is the amount of money on the gift card when Salim receives it?
$?
To find the initial amount of money on the gift card when Salim receives it, we can use the equation:
m - $7.50 = $12.50
m = $12.50 + $7.50
m = $20.00
Therefore, the initial amount of money on the gift card when Salim receives it is $20.00.
