d + b = 8
2.29d + 5.69b = 28.52

Hotdogs (d) = 2.29d
Hamburgers (b) = 5.69b
Total ( 8) = 28.52

[Hello, ssabic36]

Answer:

3 hamburger packs

5 hot dog packs

Explanation:

Knowing that:

Gary buy ⇒ 8 packages for a total of $28.52

A package of hot dogs costs $2.29 and a package of hamburgers costs $5.69.

Solving:

Let the Hotdogs = HD

Let the Hamburgers = HB

HD + HB = 8

2.29HB + 5.69HB = 28.52

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Total ( 8) = 28.52

Since we now know that

Hotdogs (HD) = 2.29

Hamburgers (HB) = 5.69

Thus,

2.29x5 = 11.45

5.69 x 3=17.07

17.07 + 11.45 = 28.52

Thus, gray buy

3 hamburger packs

5 hot dog packs
