Selena spends $53.94 to buy a necklace and a bracelet set for each of her friends. Each necklace cost 9.99, and each bracelet costs 7.99. How many necklace and bracelet sets, s, did selena buy?

She bought 3 necklace and bracelet sets

If i can be brainliest that would be great

Step-by-step explanation:

Each set contains a necklace and a bracelet

∵ Each necklace cost $9.99

∵ Each bracelet cost $7.99

∴ The cost of one set = (9.99 + 7.99)

∵ She spent on them $53.94

- Add the cost of a necklace and the cost of a bracelet and

 multiply the sum by x  and then equate the product by 53.94

∴ (9.99 + 7.99)x = 53.94

∴ 17.98 x = 53.94

- Divide both sides by 17.98

∴ x = 3

the answer is d. 75%

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
