Isabella has $6,000. she gave her mother $1,800. she donated 1/4 of the remaining amount to a charity. what percent of her money did isabella donate? *

Step-by-step explanation:

6000-1800 = 4200 divided by 1/4 = 1050

6,000 - 1,800 = 4,200

4,200 / 1/4 (or 25)

she donated 168.0% of her money.

Let x be the variable for a t-shirt for $8.
Let y be the variable for shorts for $12.
Let z be the variable for the hats that cost $10 each.

We have the expression 1 below:
$464 = $8x + $12y + $10z
other expressions:
3z = x
2z =y

By substitution we can solve each variable:

464 = 8(3z) + 12(2z) + 10z
464 = 24z +24z +10z
464 = 58z
z = 8

Solve for x andy:
3z=x
3*8 = 24=x
2z=y
2*8 = 16 = y

The t-shirts are 24 pieces, the shorts are 16 pieces and hats are 8 pieces.
