Answer:
2.75
Step-by-step explanation:
0.10 represents the rate at which prices have increased since 1980..
2.75 represents the price in 1980
This can be confirmed by inputting 0 as the value of x.
2.75+0.10(0) = 2.75
1. 9/3
This is because 3 = 3/1, and if multiplied by 3/3 becomes 9/3.
2. 4/2
See above, this time we multiply by 2/2
3. 20/4
See above, this time we multiply by 4/4
4. 5/5
See above, this time we multiply by 5/5, and since our whole number is 1, due to the identity postulate, it will equal 5/5
