Answer:
1.05
Step-by-step explanation:
shop A: 2x3= 6
shop b: 5 for 1.10, 5 more for .55, so 1.65/10
1.65×3= 4.95
6-4.95= 1.05
So in this case first add all the cost togather, 3.50+2.25+9.95=$15.7
then move the decimal left two times to make the 5% into decimal number, which is .50
and multiply it by the total cost $15.7 which is 15.7*.50=7.85.

<DFA = 180 -(66+56) = 58
<EOB = 360- (90+90+58) = 122
<COB = 360 - (90+90+66) = 114
<COE = 360 - (90+90+56) = 124 so arcCE = 124
answer
<DFA = 58
<EOB = 122
<COB = 114
arc CE = 124
I'm pretty sure the answer is B) 11c+8.5(c-46)=470
hope i help :)
