2).Elisa withdrew $20 at a time from her bank account and withdrew a total of $140. Francis withdrew $45 at a time from his bank account and withdrew a total of $270.Who made the greater number of withdrawal?justify your answer

Answer 1

Part 1)

Let

x--------> the cost of each bus ride

we know that

$12x=\ 24$

Solve for x

Divide both sides by $12$

$12x/12=\ 24/12$

$x=\ 2$

therefore

the answer part 1) is

The cost of each bus ride is $\ 2$

Part 2)

Find the number of Elisa's withdrawals

Divide the total withdrew by the withdrew at a time

so

$\frac{\ 140}{\ 20}=7\ times$

Find the number of Francis's withdrawals

Divide the total withdrew by the withdrew at a time

so

$\frac{\ 270}{\ 45}=6\ times$

$7\ times > 6\ times$

therefore

the answer Part 2) is

the greatest number of withdrawals were made by Elisa

Answer 2

1. 24÷12 =$2 $2 is the answer

2. $140÷$20=7 $270÷$45=6. Elisa and the reason is <---- the working out
