Christina works part-time from home as a data entry professional. She enters data in forms and is paid based on the entry accuracy rate. The table below shows her compensation.

Based on her regular performance, the equation below can be used to determine C, the total amount Christina earns a month entering data, where x represents the total number of forms she completes that month.

C = 15(0.8x) + 12(0.1x) + 0(0.1x)

What is the minimum number of forms she must complete in a month to earn a total of at least $1,584?

does it really say $0(0.1x)$ at the end??

anonymous · Answer

yea

anonymous · Answer

i am thinking that is a typo, and maybe it meant $10(0.1x)$

anonymous · Answer

especially since $0(0.1x)=0$

anonymous · Answer

no matter, if it really says $0(0.1x)$ then ignore that term 
$$15(0.8x)+12(0.1x)=13.2x$$

anonymous · Answer

solve 
$$1,584=13.2x$$ by dividing both sides by $13.2$
