Nathan works part-time from home as a data entry professional. He enters data in forms and is paid based on the entry accuracy rate. The table below shows his compensation.
A 2-column table with 'Accuracy' and 'Compensation per Form' as the column headings. Tier 1 is $18, Tier 2 is $12, and Tier 3 is $0
Based on his regular performance, the equation below can be used to determine C, the total amount Nathan earns a month entering data, where x represents the total number of forms he completes that month.
C = 18(0.7x) + 12(0.2x) + 0(0.1x)
What is the minimum number of forms he must complete
