As treasurer of his school's FFA club, Kenny wants to buy gifts for all 18 members. He can buy t-shirts for $9 and sweatshirts f

DanielleElmas [232]

Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:

Given,

Number of members = 18

Cost of each t shirt = $9

Cost of each sweatshirt = $15

Money = $180

Let,

x be the number of t shirts

y be the number of sweatshirts

According to given statement;

x+y=18 Eqn 1

9x+15y=180 Eqn 2

Multiplying Eqn 1 by 9

$9(x+y=18 )\\9x+9y= 162\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(9x+15y)-(9x+9y)=180-162\\9x+15y-9x-9y=18\\6y=18\\$

Dividing both sides by 6

$\frac{6y}{6}=\frac{18}{6}\\y=3$

Putting y=3 in Eqn 1

$x+3=18\\x=18-3\\x=15$

Kenny can buy 15 t shirts and 3 sweatshirts.

Solve for b.

Over [174]

Answer: A.) b= 2a/h-c

1/2h(b+c)= A

2×1/2h(b+c)=A×2

h(b+c)=2A

h÷h(b+c)=2A÷h

b+c=2A/h

b+c-c=2A/h-c

b=2A/h-c

1. A student bought two juice pouches for $1.25 each and 3 bags of chips. Write and solve an equation to determine the cost of c

zvonat [6]

<h3><u>Question:</u></h3>

A student bought two juice pouches for $1.25 each and 3 bags of chips. The total cost was $5.05 .write and solve an equation to determine the cost of a bag of chips,c

<h3><u>Answer:</u></h3>

variable : c (cost of 1 bag of chips )

equation: 2.5 + 3c = 5.05

solution: cost of 1 bag of chips = $ 0.85 and cost of 3 bags of chips = $ 2.55

<h3><u>Solution:</u></h3>

Given that, student bought two juice pouches for $1.25 each and 3 bags of chips

Let "c" be the price of 1 bags of chips

cost of 1 juice pouches = $ 1.25

Total cost = $ 5.05

<em><u>Therefore, we frame a equation as:</u></em>

two juice pouches x cost of 1 juice pouches + 3 bags of chips x price of 1 bags of chips = 5.05

$2 \times 1.25 +3\times c = 5.05$

<em><u>Solve the above equation for "c"</u></em>

$2.5 + 3c = 5.05\\\\3c = 5.05 - 2.5\\\\3c = 2.55\\\\c = 0.85$

Thus cost of 1 bag of chips = $ 0.85

Thus, cost of 3 bags of chips = $ 0.85 x 3 = $ 2.55
