Answer:
3x - 24
Step-by-step explanation:
this is probably wrong
Formula for area of a triangle is 1/2 x base x height.
musing the information given you have:
360 = 1/2 x base x 18
First multiply both sides by 2:
720 = base x 18
Now divide both sides by 18:
Base = 720/18
Base = 40 cm
Area = 1/2 (sum of bases ) *h
40 *2 = (10+6)*h
80/16 = h
5 unit = h
The average she spent is $18 because $16 + $2
