Question

Can someone help me with number 4 and 12

Answer 1

4. Say x = 100, and so the iPad was $100. One year later, the iPad's value is equal to 0.82(x) or 0.82(100) = $82. The decrease was $18 from the original value. Therefore, another way to describe the change in the value of the iPad is C. 18% decrease.

12. So the Seahawks won 16 games last year, and 20 games this year. Here is an equation we can set up to help solve the problem:

20 = 16 + 16(x)

4 = 16x

x = 0.25

Therefore, the percent increase in the number of games the Seahawks won is 25%.

Hope this helps!! :)
