A local bake shop sells cookies and cakes.On monday , sean bought 3 cookies and 5 cakes and spent $78.75 on tuesday , sean bough

Bond [772]

Answer:

The price of one cookie is $1.25 and the price of one cake is $15.

Step-by-step explanation:

Let $x be the price of one cookie and $y be the price of one cake.

1. On Monday, Sean bought 3 cookies and 5 cakes, then he spent $(3x+5y) and this is $78.75. Thus,

$3x+5y=78.75.$

2. On Tuesday, Sean bought 8 cookies and 2 cakes, then he spent $(8x+2y) and this is $40. Thus,

$8x+2y=40.$

3. Solve the system of two equations:

$\left\{\begin{array}{l}3x+5y=78.75\\8x+2y=40\end{array}\right.$

Multiply the first equation by 2 and the second equation by 5 and subtract them:

$2(3x+5y)-5(8x+2y)=2\cdot 78.75-5\cdot 40,\\ \\6x+10y-40x-10y=157.5-200,\\ \\-34x=-42.5,\\ \\x=\$1.25.$

Then

$8\cdot 1.25+2y=40,\\ \\2y=40-10,\\ \\y=\$15.$

What is the solution to the inequality 28 > 4 – 2p?

FinnZ [79.3K]

When multiply or divide an inequality by a negative number, flip the direction of the sign (ex, from < to > or vice verca)

28>4-2p
minus 4 from both sides
24>-2p
divide both sides by -2 and don't forget to flip the sign
-12<p
p>-12
