Tom has saved $128, and his goal is $500. how much more must he save.
a) x + 128 = 500
b) x - 128 = 500
c) x + 500 = 128
d) x - 500 =128
in other words, what number, added to 128, gives 500?
To find out how much more Tom needs to save to reach his goal of $500, we can subtract the amount he has saved ($128) from the goal amount ($500).
Therefore, the correct equation would be:
x = 500 - 128
Simplifying the equation:
x = 372
So, Tom must save $372 more to reach his goal.
Therefore, the correct option is:
a) x + 128 = 500
To determine how much more Tom must save to reach his goal of $500, we need to perform a subtraction operation.
We subtract the amount Tom has already saved ($128) from his goal amount ($500) to find the difference.
$500 - $128 = $372
Therefore, the correct answer is:
d) x - 500 = 128
