The Molina family went to a concert together. They purchased 4 concert tickets for $25 each, 3 t-shirts for $15 each, and a poster for $10. Write an expression for the total cost and then find the total cost.

$155

Step-by-step explanation:

Variable

Ticket=T

Shirts=S

Poster=P

4 concert ticket so 4T

3 t-shirts so 3S

Poster is P

So the Expression is: 4T+3S+P=Total cost

To find total cost:

Concert at $25 each for 4 people (multiply)

25*4=$100

3 t-shirts for $15 (multiply)

15*3=$45

Poster is $10

Add the totals together:

100+45+10= $155

Therefore, the total cost is $155 for the things they purchased.

Hope this help!!!

Have a nice day :)

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
