The greatest number of pairs of skis and snowboards the group can rent are 21 pairs of skis and 9 pairs of snowboards.

Step-by-step explanation:

Given:

A group can rent pairs of skis and snowboards by the week. They get a reduced rate if they rent 7 pairs of skis for every 3 snowboards rented. The reduced ski rate is $45.50 per pair of skis per week, and the reduced snowboard rate is $110 per snowboard per week.

The sales tax on each rental is 16%.

The group has $2,500 available to spend on ski and snowboard rentals.

If the ratio of pairs of skis to snowboards is 7:3.

Now, to find the greatest number of pairs of skis and snowboards rentals.

So, the rent of 7 pairs of skis = $7\times 45.50=\$318.50.$

And the rent of 3 pairs of snowboards = $3\times 110=\$330.$

So, total rental amount of 7 pairs of skis and 3 pairs of snowboards:

318.50 + 330 = 648.50.

Now, to get the rental amount after sales tax:

648.50 + 16% of $648.50.

$=648.50 +\frac{16}{100}\times 648.50.$

=648.50+103.76

$=\$752.26.$

The total rental amount after sales tax = $752.26.

As the group has available $2,500.

So, the sets according to the given ratio:

$2500\div 752.26 = 3.32.$

$=3\ sets.$

Thus, there are 3 sets of the ratio 7:3.

So, the rental price according to sets are:

The rent of Skis:

$7\times 3 = 21$

$21\times 45.50= 955.50$

The rent of snowboards:

$3\times 3 = 9$

$9\times 110 = 990$

So. the total rental amount of skis and snowboards according to sets are:

955.50 + 990 = 1,945.50

Now, the amount of rent after sales tax:

$1945.50 + 16% of $1945.50.

$=1945.50+\frac{16}{100}\times 1945.50$

$=1945.50+311.28=\$2256.78.$

Thus, the total cost = $2256.78.

Now, to get the greatest number of pairs of skis to snowboards that can be rent:

2,500 - 2,256.78 = 243.22

The cost of 21 pair of skis and 9 pairs of snowboards is $2256.78 and the group has available only $2500 to spend.

Thus, they can rent only 21 pairs of skis and 9 pairs of snowboards.

Therefore, the greatest number of pairs of skis and snowboards the group can rent are 21 pairs of skis and 9 pairs of snowboards.

Answer from: Quest

d. 8

step-by-step explanation:

the given radical expression is:

$\sqrt{16}\times \sqrt{4}$

we can rewrite this as:

$(16)^{\frac{1}{2}\times (4)^{\frac{1}{2}$

we express as square numbers to get;

$(4^2)^{\frac{1}{2}\times (2^2)^{\frac{1}{2}$

the exponents will now cancel out to give.

$4\times2=8$

the correct answer is d
