Question

My friend Elentine purchased 9 Naxvips for $2 each and some toys for $8 each.

Answer 1

The equations to model the relationship between Elentine's naxvips (x) and toys (y) is: Total cost = 18 + 8y

Solution:

Let "x" be the number of naxvips bought

Let "y" be the number of toys bought

From given,

Cost of each naxvip = $ 2

Cost of each toy = $ 8

My friend Elentine purchased 9 Naxvips for $2 each and some toys for $8 each.

Thus according to given we frame a equation as:

Total cost = 9 naxvips x 2 + y x 8

$Total\ cost = 9 \times 2 + y \times 8\\\\Total\ cost = 18+8y$

Thus total cost spend is (18 + 8y) dollars
