Answer:
$4.43
Step-by-step explanation:
10 bagels cost $3.69. 1 bagel costs $3.69/10=$0.369
12 bagels cost $0.369×12=$4.43
Membership is discounted $2 for first month
c=cost of one month
d=discount=$2
x=# of months
xc - 2= total cost
x for 1 month is 1, c is always 12, -2 is constant
1 x(12) - 2=10 for first month
8 months
8c -2=total cost for 8 months
8 x 12 - 2= 94 for 8 months

Answer:
20%
Step-by-step explanation:
<u><em>Given/To Find:</em></u>
<em>A $52.50 screen door is on</em>
<em>sale for $42. Find the percent</em>
<em>of discount on the door.</em>
<u><em>Solve:</em></u>
<em>Formula: Value 1 - Value 2 ÷ Original Value × 100</em>
<em />
<em>Hence we have:</em>
<em>52.50 - 42 = 10.5</em>
<em>10.5 ÷ 52.50 = 0.20</em>
<em>0.20 × 100</em>
<em>=20%</em>
<em />
<em>Check Answer:</em>
<em>52.50 × 20% = 10.5</em>
<em>52.50 - 10.5 = 42</em>
<em>Hence, the percent of discount on the door is 20%</em>
