Mark sold 218 tickets for the school play and made $1,363. Adult tickets are $8 and student tickets are $5. How many adult tickets did Mark sell?

91

Step-by-step explanation:

Let adults tickets be a

Let students ticket be b.

The information in the question can be presented as an equation as:

a + b = 218 i

8a + 5b = 1363 ii

Multiply equation i by 5

Multiply equation ii by 1

5a + 5b = 1090 iii

8a + 5b = 1363 iv

Subtract iii from iv

3a= 273

a = 273/3

a = 91

Number of adult's ticket sold = 91

step-by-step explanation:

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis
