Answer: -48m + 56
Step-by-step explanation:
-8x 6m= -48m
-8x-7= 56
They planted 714 trees I think because 51 times 14 is 714
O=orange
a=apple
equation 1
3o+a=$1.86
a=$1.86-3o
use a=$1.86-3o in equation 2
equation 2
2o+3a=$2.15
2o+3($1.86-3o)=$2.15
2o+$5.58-9o=$2.15
$5.58-7o=$2.15
$5.58=$2.15+7o
$3.43=7o
$0.49=o
then use $0.49=o for equation 1.
equation 1
3($0.49)+a=$1.86
$1.47+a=$1.86
a=$0.39
so an apple is $0.39.
Then you're pretty solid on time
