Remark
I didn't know this was a calculus question. How dumb of me.

f(x + h) - f(x)
==========
x + h  - h

50/6 - 51/6 =( -1/6+ h)/h 
The h's will disappear when the limit is taken.

answer - 1/6 which is A. If anyone else answers take their answer.

2. Meryl spends a total of $68.82 for 2 pairs of 68.8
kupik [55]

Answer:

The cost of each pair of sneakers is $33.25.

Step-by-step explanation:

Consider the provided information.

Meryl spends a total $68.82 for 2 pairs of sneakers with the same cost.

If the sales tax is $5.32 and she also uses a coupon for $3.00 off her purchase.

First subtract the sales tax from the spend amount.

\$68.82- \$5.32=\$63.5

She use a coupon for $3.00 OFF.

\$63.5+\$3=\$66.5

$66.5 was the cost of 2 pairs of sneakers before using the coupon.

Now divide $66.5 by 2 so that we can find the cost of one pair of sneakers.

\frac{\$66.5}{2} =\$33.25

Hence, the cost of each pair of sneakers is $33.25.
