bonufazy [111]
The ratio in which Adm, Ming and Clinton sold sandwiches = 4:7:3
Number of sandwiches sold by Ming = 91
Let us assume the common ratio to be = x
Then
7x = 91
x = 91/7
  = 13
Then
The number of sandwiches sold by Adm = 4 * 13
                                                                   = 52
The number of sandwiches sold by Clinton = 3 * 13
                                                                      = 39
So
The total number of sandwiches
 sold by Adm, Ming and Clinton = 52 + 91 + 39
                                                  = 182.
So a total of 182 sandwiches were sold by Adm, Ming and Clinton.

A recipe for apple sause calls for 1/3 cup of honey. The recipe makes 8 servings. How many cups of honey are needed to make 20 s
Komok [63]
To make exactly 20 servings, we need to know how much honey is used for exactly one serving.
Given that 1/3 cup of honey equates to 8 servings, divide 1/3 by 8 to get the amount of honey needed for 1 serving.
Then, to figure out how much honey is needed for 20 servings, simply multiply that result by 20.

Hope this helps!

Jess deposited $5,000 into an account that earns simple interest. After 9 years, Jess had earned $3,150 in interest. What was th
musickatia [10]

Answer:

The interest rate of Jess's account was 7%

Step-by-step explanation:

A = P * (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the values we know:

A =  P * (1 + rt)

8,150 = 5,000 * (1 + r * 9)

8,150/5,000 = 1 + 9r

1.63 = 1 + 9r

1.63 - 1 = 9r

0.63 = 9r

r = 063/9

r = 0.07 = 7%

The interest rate of Jess's account was 7%
