John and his friend ordered lunch at a local sandwich shop. They each ordered a soft drink that costs $1.65. John orders a whole
ExtremeBDS [4]

Answer:

a. $12.54 = $ 1.65 + c/2 + c b. $ 7.26

Step-by-step explanation:

a. What equation can you use to find the cost c of a sandwich

Let c be the cost of a whole ham sandwich. Now, the total bill = cost of drinks + cost of half a ham sandwich  + cost of a whole ham sandwich.

total bill = $ 12.54, cost of drinks = $ 1.65, cost of half a ham sandwich = c/2 and cost of a whole ham sandwich = c. So,

$12.54 = $ 1.65 + c/2 + c

b. What is the value of c

We then solve for c in the equation $12.54 = $ 1.65 + c/2 + c

collecting like terms, we have

$12.54 - $ 1.65 = c/2 + c

$ 10.89 = 3c/2

multiplying through by 2, we have

$ 10.89 × 2 = 3c

$ 21.78 = 3c

dividing through by 3, we have

c = $ 21.78/3

= $ 7.26

FinnZ [79.3K]

Step-by-step explanation:

48 = 48 \times 1 \\ 48 = (24 \times 2) \times 1 \\ 48 = (12 \times 2) \times 2 \times 1 \\ 48 = (6 \times 2) \times 2 \times 2 \times 1 \\ 48 = (3 \times 2) \times 2 \times 2 \times 2 \times 1

Find the sticker price and dealer's cost for the Tarop Series car. The base price given is $24,990.00. The options for the Tarop
podryga [215]

Alright, lets get started.

The base price is given : $ 24990

The dealer pays 76% of the base price means

he pays for base price : 24990 * \frac{76}{100}

he pays for base price : $ 18992.4

For options, total : 868 + 452 + 1260 = 2580

He pays 88% for options, means

he pays for options : 2580 * \frac{88}{100}

he pays for options : $ 2270.4

So, total dealer pays : 18992.4 + 2270.4 + destination charges

So, total dealer pays : 18992.4 + 2270.4 + 630 = $ 21892.8

Hence dealer's cost : $ 21892.8

Price of sticker will be : 24990 + 868 + 452 + 1260 + 630

Price of sticker will be : $ 28200

dealer's cost : $ 21892.8

Hope it will help :)
