gogolik [260]

Answer:

The percent increase between getting a high school scholarship and bachelor's degree is <u>59.14%</u>.

Step-by-step explanation:

Given:

High school scholarship is $421.

Bachelor's degree is $670.

Now, to find the percent increase between a high school scholarship and bachelor's degree.

So, we get the amount of increase between a high school scholarship and bachelor's degree.

$670-421=249.$

<em>Thus, the amount of increase = $249</em>.

Now, to get the percent increase between a high school scholarship and bachelor's degree:

$\frac{249}{421}\times 100$

$=\frac{24900}{421}$

$=59.14\%.$

Therefore, the percent increase between getting a high school scholarship and bachelor's degree is 59.14%.

Answer:

Coupon B

Step-by-step explanation:

Given

$Price = \$450$

$Coupon\ A = \$80$

$Coupon\ B = 20.5\%$

Required

Which coupon is better

From the question, we have:

$Coupon\ A = \$80$

Coupon B means that:

$Coupon\ B = 20.5\% * \$450$

$Coupon\ B = 0.205 * \$450$
