2^3 * 7 + 7^2

Step-by-step explanation:

1) divide 28 by 2 = 14

2) divide 14 by 2 = 7

3) this means that 2 * 2 * 7 = 28

4) you can then take those 2 twos and multiply them with the first 2 and make 2^3

5) the square root of 49 is 7 so that is just 7^2

6) plug in all these new values for the originals and you get the answer above

first you gotta calculate 2 -28 +49

After getting the answer solve the expressions to see which one is equivalent to 2-28 +49 (I think)

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
