The center for science and industry sells adult tickets $15 and children’s tickets for $4. the expression 15a+4c represents the total revenue from selling a adult ticket and c children’s tickets. evaluate the algebraic expression 15a + 4c for a =179 and c =451
To evaluate the algebraic expression 15a + 4c for a = 179 and c = 451, substitute the values into the expression:
15(179) + 4(451)
Multiply:
2685 + 1804
Add:
4489
The total revenue from selling 179 adult tickets and 451 children's tickets would be $4489.
To evaluate the algebraic expression 15a + 4c, we substitute the values of a and c into the expression.
Given:
a = 179
c = 451
Substituting these values into the expression, we have:
15a + 4c = 15(179) + 4(451)
Now we can perform the multiplication and addition:
15a + 4c = 2,685 + 1,804
Now, adding the two numbers:
15a + 4c = 4,489
Therefore, the value of the expression 15a + 4c when a = 179 and c = 451 is 4,489.
To evaluate the expression 15a + 4c for a = 179 and c = 451, you need to substitute the given values into the expression and perform the calculations.
Here's the step-by-step process:
1. Replace the variable "a" with the given value of 179.
15a + 4c = 15(179) + 4c
2. Multiply 15 by 179.
15(179) = 2,685
3. Replace the variable "c" with the given value of 451.
2,685 + 4c = 2,685 + 4(451)
4. Multiply 4 by 451.
4(451) = 1,804
5. Add the calculated values together.
2,685 + 1,804 = 4,489
Therefore, when a = 179 and c = 451, the value of the expression 15a + 4c is 4,489.
