The company charges $75 for each tree planted and $20 for each bush. Mrs. Grijalva was billed for $810 after the planting was complete. How many bushes did the company plant in Mrs. Grijalva’s back yard? A. 2 B. 6 C. 18 D. 54

Answer 1

B=3T
the bushes cost $20 each, and the trees costs $75 each
=$20*B+$75*T
the total cost was $810
810=20B+75T
810=20(3T)+75T
810=135T
T=6 plug into formula
B=3T=3(6)=18
