Answer:
Step-by-step explanation:
1 toy car is 3 so if you multiply it by 4 becuase theres 4 cars you get 12
he paid $12
he sells one car for $5 so multiply it by 4
and he would get $20 dollars wich is only $8 more dollars
A= 1/2(bh)
h=4b
50= (1/2)(b*4b)=2b^2
25=b^2
base = 5 that's your answer
height = 4xb = 4x5=20
We can use the is/of=p/100 method for this problem. Since it's 15% off, this would mean that the bill is 85% of what it was initially. Plug the values into the is/of=p/100 formula.
36.72/x = 85/100
Solve for x.
x=36.72/0.85
x=43.2
So, the bill was $43.20 before applying the voucher discount of 15% off.
Your answer would be 3 8/35
