Lulu brought each of her friends a pair of colorful socks that cost $5.50. Write an equation that shows the total cost, c, for p pairs of socks *
Your expression is correct! To find the change in the amount of money Mrs. Armor had, you need to add up all the money she spent and subtract any money she found.
The expression is:
7 * 3 + 12 + 5
Let's evaluate the expression:
7 * 3 = 21
21 + 12 = 33
33 + 5 = 38
So, the value of the expression is $38. Therefore, the change in the amount of money Mrs. Armor had over the course of Saturday is $38.
by finding $5 on the sidewalk, is that the change in the amount of money mrs. armor had? just $5 ??
tank you very much ms. sue !!
After she'd spent $33, how could she have more money than she started with?
-33 + 5 = -$28
She has $28 less than when she started.
