mark sold 461 tickets for the school play.

student tickets cost $3 and adult tickets cost $4. mark's sales totaled $1624.

write and solve a system of equations to determine how many adult and student tickets mark sold?

a. 220 adult, 241 student

b. 236 adult, 225 student

c. 241 adult, 220 student

d. 225 adult, 236 student

Step-by-step explanation:

3s+4a=1624

S+a=461

3s+3a=1383

(3s+4a=1624)

-(3s+3a=1383)

0+a=241

A=241

241 adult tickets were sold

S+a=461

S+241=461

S=220

220 student tickets were sold

You can check by doing: (220×3)+(241×4)=1624

S=student tickets

A=adult tickets

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
