#12. how is the answer 48? how do i get it?

Alright, so we've established that the true answer is 48, but we need to understand how to get that.

We know the equation is (t/4) - 3 = 9

First, we need to add 3 to both sides. You should come up with: t/4 = 12

Now, when you have a fraction like that, you need to multiply by the denominator on both sides, no matter what the numerator may be. Therefore:

t/4 (4) = 12(4)

t = 48

As another example to enhance your understanding, let's use (x/5) - 6 = 10.

You'd begin by adding 6 to each side: (x/5) = 16.

Then, multiply by 5 (the denominator) on both sides.

x = 80.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
