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.

A 2-column table with 'Accuracy' and 'Compensation per Form' as the column headings. Tier 1 is $15, Tier 2 is $12, and Tier 3 is $0

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? 

I'm thinking C is for $1,584

thanks for no help . lel 

1584=15(0.8x)+12(0.1x)+0(0.1x)
1584=12x+1.2x+x
1584=13.2x
1584/13.2 = 13.2/13.2
x=120

Hah you're hiding in the bushes! :3

Hmmmm, ya it looks like you did that correctly. Good job! \c:/

zepdrix · Answer

That second line should have been:
1584=12x+1.2x+0x

But looks like that's what you meant anyway.
