Andy bought 4 hamburgers snd 2 milkshakes for $13.50. Danny bought 3 hamburgers and 1 milkshake for $9.25. What cost of a hambur

Molodets [167]

A hamburger costs $2.5 and a milkshake costs $1.75

Step-by-step explanation:

Step 1: Form equations from the given details. Let cost of 1 hamburger be H and cost of 1 milkshake be M.

4H + 2M = 13.50 ------ (1)

& 3H + 1M = 9.25 ------ (2)

Step 2: Multiply eq(2) with 2 to make coefficients of M equal.

6H + 2M = 18.50 ------- (3)

Step 3: Subtract eq(3) from eq(1)

⇒ - 2H = - 5

⇒ H = $2.5

Step 4: Substitute value of H in eq(2) to find M.

⇒ 3 × 2.5 + M = 9.25

⇒ 7.5 + M = 9.25

⇒ M = $1.75

PLEASE HELP WITH THIS QUESTION!! DUE BY 1PM! wILL RATE YOU GOOD!! THANK YOU!!

Find $a_{1}$ by plugging in 1 into n:
$a_{1} = 98-2(1)=96$

Find $a_{11$ by plugging in 11 into n:
$a_{11} = 98-2(11)$
$a_{1} =98-22=76$

Now to find the sum your formula is:
$S_{n} = \frac{n}{2} ( a_{1} + a_{n})$
$n = 11, a_{1} = 96 , a_{11} =76$

Now plug that into the formula
$S_{11} = \frac{11}{2} (96+76)$
$S_{11} = 5.5(172)=946$

Hope that helps
