Atoy manufacturer makes a toy truck, a toy car, and a toy boat. the production spreadsheet is: toy time to produce cost to produce profit for each truck 10 minutes $1.00 $1.00 car 12 minutes $0.75 $1.50 boat 8 minutes $0.80 $0.60 after accounting for breaks, a worker actually works 400 minutes each day. the manufacturer needs each worker to generate a potential profit of $35 each day. write a system of inequalities that expresses these constraints

                 time                    profit               number
truck          10 min              1.00dollar         t
car             12min               1.50 dollar        c
boat           8min                 0.60 dollar        b

let the worker produce t trucks, c cars, and b boats.
10t+12c+8b=400
t+1.5c+0.6b is more than or equal to 35
t is more than or equal to 0
c is more than or equal to zero
b is more than or equal to zero

(this question is kinda wierd. i do not know if i am correct, because mine is not exactly a system of inequalities, but if you really need an answer, you can try this one.)

2xy/9 is the answer to this problem
