elena55 [62]

Answer:

89 is  the maximum number of guests that can be invited within budget  .

Step-by-step explanation:

The cleaning charges = $55

Total budget available = $3350

Cost per guest = $37

Now, actual budget available for guest = Total budget -  Cleaning Fee

= $3350  - $ 55   = $3,295

Now, cost per head =$ 37

So, number of guests (n) possible in the budget

⇒ n = (Total guest Budget)/ Cost per head

= $3,295 / $37  = $89.05

or,  n = $89.05

So, 89 is  the maximum number of guests that can be invited within budget  .

Pachacha [2.7K]

Answer:

given,

Amount borrowed = $71500

Time = 200 days

interest rate = 7.5 %

ordinary interest rate for year = 71500\times \dfrac{7.5}{100}

                                                  = $5362.5

exact interest rate for the year = 71500\times \dfrac{7.5}{100}\times \dfrac{200}{365}

                                                   = $2938.35

hence, the exact interest rate is less than the ordinary interest rate which means you should choose exact interest rate.
