Answer:
1. 20 for $1.56 =A. 7.8 cents each
2. $3.78 for 6=B. 63 cents each
3. [tex]2\frac{1}{2}[/tex] or one dollar =C. 40 cents each
4. 5 at $3.90 = D. 78 cents each
5. [tex]1\frac{1}{2}[/tex] for $1.58 = E. $1.05 each
Step-by-step explanation:
1. 20 for $1.56
Since cost of 20 items = $1.56
So, cost of 1 item = [tex]\frac{1.56}{20}[/tex]
=$0.078
1 dollar = 100 cents
So, $0.078= 0.078 * 100 =7.8 cents.
2. $3.78 for 6
Since cost of 6 items = $3.78
So, cost of 1 item = [tex]\frac{3.78}{6}[/tex]
=$0.63
1 dollar = 100 cents
So, $0.63 = 0.63 * 100 =63 cents.
3. [tex]2\frac{1}{2}[/tex] for one dollar
Cost of [tex]2\frac{1}{2}=\frac{5}{2}[/tex] = $1
So, cost of 1 item = [tex]\frac{1}{\frac{5}{2}}[/tex]
= [tex]\frac{2}{5}[/tex]
1 dollar = 100 cents
So, $[tex]\frac{2}{5}[/tex]=[tex]\frac{2}{5}\times100[/tex] =40 cents.
4. 5 at $3.90
Since cost of 5 items = $3.90
So, cost of 1 item = [tex]\frac{3.90}{5}[/tex]
=$0.78
1 dollar = 100 cents
So, $0.78= 0.78 * 100 =78 cents.
5. [tex]1\frac{1}{2}[/tex] for $1.58
Cost of [tex]1\frac{1}{2}=\frac{3}{2}[/tex] = $1.58
So, cost of 1 item = [tex]\frac{1.58}{\frac{3}{2}}[/tex]
= [tex]1.05[/tex]
Thus,
1. 20 for $1.56 =A. 7.8 cents each
2. $3.78 for 6=B. 63 cents each
3. [tex]2\frac{1}{2}[/tex] or one dollar =C. 40 cents each
4. 5 at $3.90 = D. 78 cents each
5. [tex]1\frac{1}{2}[/tex] for $1.58 = E. $1.05 each
