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

Answer: 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

Answer: 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

Answer: 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

Answer: $21.50 + 0.2r

Beach Cruises prints brochures and fliers to advertise their dolphin watching tours. To print, the brochure requires three pages
Ivanshal [37]

Answer:

To minimize their costs, Beach Cruises should print 80 brochures and 130 fliers.

Step-by-step explanation:

Total number of sheets available = 500 sheets

For brochures;

1 brochure contains 3 pages

Minimum number of brochures that should be printed = 80

Cost of 1 brochure = 10 cents

Number of sheets required to print 80 brochures = 80 × 3 = 240 sheets

For fliers;

1 flier contains 2 pages

Minimum number of fliers to be printed = 100

cost of 1 flier = 6 cents

Number of sheets required to print 100 fliers = 100 × 2 = 200 sheets

Total number of sheets that will be used to print at least 80 brochures and 100 fliers = 240 + 200 = 440 sheets

number of sheets left = 500 - 440 = 60 sheets

After Beach cruises have printed the minimum required 80 brochures and 100 fliers, they are left with 60 free sheets of paper.

Since it is cheaper for Beach cruises to print fliers (at 6 cent per flier) than brochures (at 10 cent per brochure), then it is advisable to use the remaining 60 sheets to print fliers, so as to minimize costs.

Since 1 flier contains 2 pages,

with 60 sheets, the number of fliers that can be printed = 60/2 = 30 fliers

cost of 30 fliers = 30 × 6 cents = 180 cents

If the remaining 60 sheets are used to print brochures;

1 brochure has 3 pages,

therefore number of brochures to be printed = 60/3 = 20 brochures

cost of 20 brochures = 20 × 10 cents = 200 cents

This is why it is cheaper to print extra fliers at 180 cents.

Therefore total number of prints will be;

Brochures = 80

Fliers = 100 + 30 =130

Complementary angles ⇒ the angles add up to 90°

∠A and ∠B are complementary ⇒ ∠A + ∠B = 90°

∠A + ∠B = 90°

Plug in the values for ∠A and ∠B:
(3x - 8) + (5x + 10)  = 90

Open the brackets:
3x - 8 + 5x + 10 = 90

Combine like terms:
8x + 2 = 90

Subtract 2 from both sides:
8x = 88

Divide both sides by 8:
x = 11

Answer: x = 11
