the regular shipping fee (in dollars) for an online computer store is given by the expression 0.5w + 4.49 where w is the weight (in pounds) of the item. the fee (in dollars) for rush delivery is given by 0.99w + 6.49. You purchase a 26.5 pound computer. How much do you save by using regular shipping instead of rush delivery?

Respuesta :

Answer:

$ 14.99

Step-by-step explanation:

regular shipping :

0.5w + 4.49.....w = 26.5

0.5(26.5) + 4.49 = $ 17.74

rush delivery :

0.99w + 6.49....w = 26.5

0.99(26.5) + 6.49 = $ 32.73

so u would save : (32.73 - 17.74) = $ 14.99 by using regular shipping
