Sidney is eating lunch at a salad bar where you create your own salad. An 8-ounce salad costs $2.49. Each additional ounce of salad costs $0.25. How much does Sidney's salad cost if it weighs 1 pound, 8 ounces?

6.49

Step-by-step explanation:

2.49 + 0.25(16)

2.49+4

6.49

$6.49

Step-by-step explanation:

1 lb = 16 oz

His salad weighs 1 lb, 8 ounces which is the same as 16 ounces plus 8 ounces.

8 ounces cost $2.49

His salad weighs 16 ounces more than 8 ounces, so in addition to the $2.49, he needs to pay $0.25 per ounce for 16 extra ounces.

16 * 0.25 = $4.00

Total cost = $2.49 + $4.00 = $6.49

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
