Answer:

Discount before the Coupon

Step-by-step explanation:

The cost of two paperbacks at $8 each=2 X $8 =$16

First, we determine for the case in which the coupon is applied first.

If the $4 Coupon is applied,

Cost=$16-$4 = $12

If the 10% discount is further applied,

Amount to be paid = $12-(10% of $12) =$12-1.2= $10.8

However if the discount is applied first,

Book Cost=$16-(10% of $16)=16-1.6=14.4

If the Coupon is then applied,

Amount to be paid= $(14.4-4)=$10.4

Since $10.4 is less than $10.8, we conclude therefore that it is less expensive to apply the discount first.

Answer:

The money Rachael plan to collect for the shelter is <u>$345</u>.

Step-by-step explanation:

<u><em>There are some data missing in the question, so below is the complete question:</em></u>

Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?

Now, to find the money Rachael plan to collect for the shelter.

Let the total money Rachael plan to collect be x.

The amount far she has collected = $245.

Percentage of amount she hopes to collect = 70%.

Now, to get the total money Rachael plan to collect:

70\%\ of\ x=245

\frac{70}{100} \times x=245

0.70x=245

<em>Dividing both sides by 0.70 we get:</em>

x=\$345.

Therefore, the money Rachael plan to collect for the shelter is $345.
