i.e. 
Objective of test : Whether the statement made in the advertisement is false
i.e.
Since '=' signs is contained by Null hypothesis and alternative hypothesis is against it.
So the null and the alternative hypotheses for the test will be:

so change a value to a percentage format, we simply divide it by 100.
for example, 2% can be rewritten as 2/100 or 0.02 in decimal format.
now, let's first convert the mixed fraction to improper, and then do the percentage format and simplification.

Answer:
She needs at least 11 pieces of accessories.
Step-by-step explanation:
She needs $200 and she has $45
