Mathematics
1 answer:
V125BC [204]3 years ago
6 0

Answer:

$6.50

Step-by-step explanation:

Let the cost of a bowl and a jug be $b and $j respectively.

3b +j= 13.70 -----(1)

j= b +4.10 -----(2)

Substitute (2) into (1):

3b +b +4.10= 13.70

4b +4.10= 13.70 <em>(</em><em>simplify</em><em>)</em>

4b= 13.70 -4.10 <em> (-4.10 on both sides)</em>

4b= 9.60

b= 9.60 ÷4 <em>(÷4 on both sides)</em>

b= 2.40

Substitute b= 2.40 into (2):

j= 2.40 +4.10

j= 6.50

Thus, the jug costs $6.50.
