Problem 1

Jahmal has p pairs of shoes.: p

Kyle has one less than five times as many pairs of shoes as Jahmal.: 5p - 1

Total: p + 5p - 1 = 6p - 1

6p - 1

Problem 2

The problem gives the original price as g. there is no s mentioned in the problem, so I don't see how you can express the higher price in terms of s. Of course, it could be that the original price is s, not g, so then just replace g with s in my answer.

The new price is g plus 15% of g.

g + 15% of g =

= g + 0.15g

= 1.15g

1.15g

Problem 3

One package of markers costs m. 7 packages of markers cost 7m. Now you need to add 9% of 7m to 7m. If you consider 7m to be 100%, if you add 9% to 100%, you get 109%, so you need to express 109% of 7m. To find a percent of a number, multiply the percent by the number. To find 109% of 7m, multiply 109% by 7m.

109% * 7m = 1.09 * 7m = 7.63m

7.63m

Problem 4

She earns $2.15 per hour and works 10 hours.

$2.15/hour * 10 hours = $21.50

From her salary, she earns $21.50 for the 10-hour shift.

Her customer receipts totaled r, and she earns 20% of r in addition to her salary. 20% of r = 0.2r. She earns $21.50 + 0.2r

$21.50 + 0.2r
