Calculate (a) the total installment price, (b) the carrying charges, and (c) the number of months needed to save the money at the monthly rate to buy the item below for its cash price (remember to round up). a computer with a cash price of $750, offered on the installment plan for $39 per month for 24 months. a. $ a0 b. $ a1 c. a2

Step-by-step explanation:

(a) $39 for 24 months comes to ...

  $39 × 24 = $936

(b) The "carrying charges" are the difference between the cash price and the installment price:

  $936 -750 = $186

(c) Saving at the rate of $39 per month, it would take ...

  $750/$39 = 19.23 . . . . months

about 20 months to save up the cash price.

Often, such savings would come from a once-a-month paycheck, so it would take more than 19 such paychecks to save the required amount.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
