Final answer:
Mia must tune up at least 46 bicycles to earn her goal of $2500, as she earns $55 per bicycle and cannot tune up a fraction of a bicycle.
Step-by-step explanation:
Mia wants to earn $2500 in her job at a bicycle store and is paid $55 for each bicycle she tunes up. To find out the minimum number of bicycles she needs to tune up to reach her goal, you would divide the total amount she wants to earn ($2500) by the amount she earns per bicycle ($55).
The calculation is as follows:
2500 รท 55 = 45.4545...
Since Mia cannot tune up a fraction of a bicycle, she would have to tune up at least the next whole number of bicycles, which is 46.
So, Mia needs to tune up at least 46 bicycles to meet or exceed her goal of $2500.
