Question

Pam spelled 68 of 100 words correctly on the pretest. How many words did she miss? If she learns 8 of those each day, how long will it take her to learn them all?

Answer 1

Pam missed 32 words in her pretest.

It will take 4 days for Pam to learn all missed words.

Explanation:

Given:

Number of words spelled correctly = 68

Total number of words on the pretest = 100

We need to find the number of words she missed.

Solution:

now we can say that;

Number of words she missed can be calculated by subtracting Number of words spelled correctly from Total number of words on the pretest.

framing in equation form we get;

Number of words she missed =
`100 -68 =32\ words`

Hence Pam missed 32 words in her pretest.

Now Given:

Number of words missed learned each day = 8

Total number of words missed = 32 words.

We need to find how long will take to learn them all.

now we can say that;

days required to learn missed words is equal to total number of words missed divided by Number of words missed learned each day.

framing in equation form we get;

Days required to learn missed words =
`(32)/(8)=4\ days`

Hence It will take 4 days for Pam to learn all missed words.
