for every set of smart kids magazine sold, Joyce was paid $11.80.
She also received a bonus of $58.40 for selling every 12 sets.
Monica received a total of $ 2600 from the sale of smart kids magazine sets in a particular month.
How many sets did she sell that month?
:
let s = no. of magazine sets
:
11.80s + (58.40) = 2600
multiply eq by 12 to get rid of the denominator
141.6s + 58.40s = 31200
200s = 31200
s = 31200/200
s = 156 magazine sets sold that month
:
:
Confirm this
11.8(156) = 1840.8
58.4(156/12) = 759.2
---------------------
total amount: 2600
