Here are the solutions to the problems:

Cashier Deposit Problem:
A cashier deposits sh 9700 in one day. How much money does he deposit in five days?

Identify the daily deposit and the number of days.
Daily deposit = sh 9700
Number of days = 5
Multiply the daily deposit by the number of days.
$9700 \times 5 = 48500$
The cashier deposits $\boxed{\text{sh } 48500}$ in five days.

Question 10:
Estimate the products of each of the following by using friendly factors.

a) $7199 \times 68$
Round 7199 to the nearest hundred.
$7199 \approx 7200$
Round 68 to the nearest ten.
$68 \approx 70$
Multiply the rounded numbers.
$7200 \times 70 = 504000$
The estimated product is $\boxed{504000}$ .

b) $9192 \times 26$
Round 9192 to the nearest hundred.
$9192 \approx 9200$
Round 26 to the nearest ten.
$26 \approx 30$
Multiply the rounded numbers.
$9200 \times 30 = 276000$
The estimated product is $\boxed{276000}$ .

c) $8876 \times 35$
Round 8876 to the nearest hundred.
$8876 \approx 8900$
Round 35 to the nearest ten.
$35 \approx 40$
Multiply the rounded numbers.
$8900 \times 40 = 356000$
The estimated product is $\boxed{356000}$ .

Question 1:
Find the missing number in each of the following.

a) $16, 32, 64, 128, \underline{\hspace{1cm}}$
Identify the pattern by finding the ratio between consecutive terms.
$32 \div 16 = 2$ $64 \div 32 = 2$ $128 \div 64 = 2$
The common ratio is 2, meaning each term is multiplied by 2 to get the next term.
Multiply the last given term by the common ratio to find the missing number.
$128 \times 2 = 256$
The missing number is $\boxed{256}$ .
