Answer:
110°
Step-by-step explanation:
t+(t+10)+(t+20)=180
t+t+10+t+20=180
3t=180-10-20
3t=150
t=50°
t+20=50+20
=70
180-70=110°
Let total amount spent =x
Dita spent 35 % of total amount.
35% of x = 0.35x
So amount spent by Dita = 0.35x
% of money spent by Benton = 20 % of x = 0.2x
We are given that Benton spent $12 more than Claire,
so making equation we have ,
Money spent by Dita = Money spent by Claire +12



x=80
So total amount spent was $80.
Money spent by Benton = 0.2x = 0.2 * 80= $16
So amount spent by Benton is $16.
90/12=7.5.
so.....
7.5 times 15 is 21.
That added to the orginal amount equals to : 111.
How much the athletic director will pay to buy 15 more sun visors is $111.
