Question

You are buying 12-packs of Mountain Dew for $\text{4.50}4.50 each and have a gift card worth $77. The function m\left(x\right)=4.50x-7m(x)=4.50x−7 represents the total cost m\left(x\right)m(x) if you buy xx 12-packs of Mountain Dew and use the gift card. How much would you pay to buy 44 12-packs of Mountain Dew?

Answer 1

$191

Explanation:

The function is given by :

m(x) = 4.50x-7 ...(1)

Where

m(x) is the total cost if you buy x 12 packs of Mountain Dew.

We need to find the cost you pay to buy 44 12-packs of Mountain Dew

Put x = 44 in equation (1), we get :

m(x) = 4.50(44)-7

m(x) = 198-7

m(x) = $191

Hene, the cost for 44 12- packs of Mountain Dew is $191.
