For the animal shelter, Elena Nppurchased
Naddik [55]

Elena's total cost (C) is 5(9.98 + 24.99 + x)

Since each dog leashes cost $9.98, each bag of dog food cost $24.99 and each crate of egg cost $x, hence:

Total cost (C) = 5 * $9.98 + (5 * 24.99) + (5 * x)

C = 5(9.98 + 24.99 + x)

Therefore Elena's total cost (C) is 5(9.98 + 24.99 + x)

Plz help this should be easy and I will give brailiest
oee [108]

Answer:

Step-by-step explanation:

x - represents 1 point shots

(54 - x) - represents 2 point shots

x + 2(54 - x) = 89

x + 108 - 2x = 89

-x + 108 = 89

x = 19 (1 point shots)

54-x = 35 ( 2 point shots)

Test:

19 + 35 = 54 (total shots)

19 x 1 = 19

35 x 2 = 70

70 + 19 = 89 points
