Question

8.The cost of four scarves and six hats is $52.00. The cost of two hats is $1.00 more than the cost of one

Answer 1

Cost of a scarf = s
cost of a hat = h

4s + 6h = 52 --------------eqn(1)
2h = s + 1  ----------------eqn(2)

Solving the equations, we get s = $7
Answer is D

Answer 2

Answer:

The answer is the option D

$\ 7.00$

Step-by-step explanation:

Let

x------> the cost of one scarf

y-----> the cost of one hat

we know that

$4x+6y=52$ -----> equation A

$2y=x+1$

$y=\frac{x+1}{2}$ ----> equation B

Substitute equation B in equation A

$4x+6(\frac{x+1}{2})=52$

Solve for x

$4x+3(x+1)=52$

$7x+3=52$

$7x=49$

$x=\ 7.00$

therefore

the cost of one scarf is $\ 7.00$
