I would say 30,40,50 because it equals the degrees of a right triangle which is 120
50 percent out of 80 is 40
If you solve it into point-slop form, the equation is y = -3x + 20, then put into standard form is 3x + y = 20. That's your answer.
If you wish to<u> mentally estimate</u> the <u>total cost</u> of items, <u>rounding </u>off the items to the<u> nearest half dollar</u>, then you have to consider all five items separately.
Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.
1. $1.85≈$2;
2. $0.98≈$1;
3. $3.49≈$3.50;
4. $9.78≈$10;
5. $6.18≈$6.
Then the total cost is
$2 + $1 + $3.50 + $10 + $6 =$22.50.
