To buy a truck you can pay $13,000 cash or put down $4250 and make 24 monthly payments of $595.54. How much would you save by pa
-Dominant- [34]

Savings by paying cash is $1,289.6.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

To buy a truck cash payment = $13,000

And, Put down cash = $4250

Now, Calculate the total amount with payments;

Total amount with payment = Payment amount * Total month

                                          = $595.54 * 24

                                          = $14,289.6

And, Calculate the total amount saved by paying cash;

Savings by paying cash = Total amount with payments - Cash payment

                                    =  $14,289.6 - $13,000

                                    = $1,289.6

Hence, Savings by paying cash is $1,289.6.

Pip, Angad and Nick share some sweets in the ratio 4:4:1. Pip gets 20 sweets. How many
Likurg_2 [28]

Answer:

45

Step-by-step explanation:

The 4 part of the ratio represents Pip's 20 sweets

Dividing 20 by 4 gives the value of one part of the ratio

20 ÷ 4 = 5 sweets ← value of 1 part of the ratio

Thus

Pip gets 20 sweets

Angad gets 20 sweets ( 4 parts of the ratio )

Nick gets 5 sweets ( 1 part of the ratio )

Total number of sweets = 20 + 20 + 5 = 45
