One day a store sold 21 sweatshirts. white ones cost​ $9.95 and yellow ones cost $ 11.50. in​ all, ​$235.30 worth of sweatshirts
FromTheMoon [43]
For this problem you have yo set up two equations.

White shirts = w Yellow shirts = y

1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30

Now we're going to do system of equations using substitution.

If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.

9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.

Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.

w + y = 21
4 + y = 21
y = 17

So 17 yellow shirts were sold and 4 white shirts were sold.

Isabella bought 4 1/4 pounds of watermelon for $14.88. What is the price, in dollars, of 1 lb of watermelon?
Harman [31]

Answer: The correct answer is $ 3.50 per pound. If she buys 4 1/4 pound, we convert the 1/4 to the decimal 0.25. Take the total cost of $14.88 and divide it by 4.25, the amount of watermelon she bought and it equals $3.50 per pound.

14.88/4.25= 3.50
