Last year 8x people came to a party. this year, the number of people increased by 125%. write an expression for the total amount of people at the party this year in terms of x

18x

Step-by-step explanation:

Last year, 8x people came to a party

Total number of people that came last year is 8x where x must be a whole number.

This year, the number of people increased by 125%. This means that 8x (total number of people for last year) increased by 125% which is a very big increment.

Total amount of people at the party this year would be

total amount of people at the party last year + 125% of total amount of people at the party last year.

An expression for the total amount of people at the party this year in terms of x would be

8x + (125/100 × 8x)

= 8x + 1.25×8x

= 8x + 10x = 18x

ok then what happened.
