Answer:
They have 425 candy bars ready to sell.
Step-by-step explanation:
Let,
x be the number of candy bars ready to sell
y be the number of chips ready to sell
According to given statement;
x+y=575 Eqn 1
x+0.5y= 500 Eqn 2
Subtracting Eqn 2 from Eqn 1
(x+y)-(x+0.5y)=575-500
x+y-x-0.5y=75
0.5y = 75
Dividing both sides by 0.5

Putting y=150 in Eqn 1
x+150 = 575
x = 575-150
x = 425
Hence,
They have 425 candy bars ready to sell.
Answer:
32.40
Step-by-step explanation:
The shirts were 40% of the regular price
The sale price of 1 shirt was
18*40% = sale price
18*.40 =7.20
He bought 3 shirts, so multiply by 3
3 * 7.2 =21.60
He paid 21.60
The price he would have paid without the discount is
18*3 = 54
The savings is
54- 21.60 =32.40
