From $18 to $45 find each percent increase round to the nearest percent

Greetings!

250%

Step-by-step explanation:

To find the percent increase, divide the end amount by the primary amount:

45 ÷ 18 = 2.5

Now simply multiply this value by 100:

2.5 x 100 = 250

So the percent increase is 250%!

Hope this helps!

The scale factor of what ?

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
