Tree pruning company a charges a one time $100 fee and $50 for each tree that they prune. tree pruning company b charges a one time $80 fee and $60 for each tree that they prune.
let the variable t represent the amount trees pruned and c represent the cost. for how many pruned trees will the cost be the same for both companies?
which system of equations can be used to solve this problem?
{c=100−50t c=80−60t
{c=50+100t c=60+80t
{c=150t c=140t
{c=100+50t c=80+60t
