Step-by-step explanation:
PLEASE MAKE ME BRANLIEST
$10 multiply by .80 is $8
$10-$8 is $2 is sale price do this for all items.
$1 is .20 cents
$4 is .80 cents
$55 is $11
$120 is $24
The answer is f(x) I’m not quite sure what
Brother one: x
Brother two: x + 15
---
Make them add up to 55 in an equation.
x + (x + 15) = 55
Combine like terms.
2x + 15 = 55
Subtract 15 from both sides.
2x = 40
Divide both sides by 2.
x = 20
Plug 20 for x into brother two.
(20) + 15 = 35
Brother one has saved $20, brother two has saved $35.
