Answer:
The cost of the doll is $11.75
Step-by-step explanation:
Let
x ----> the cost of the doll
y ----> the cost of the toy t-rex
we know that
[tex]x+y=33[/tex] -----> equation A
[tex]y=x+9.50[/tex] ----> equation B
substitute equation B in equation A and solve for x
[tex]x+(x+9.50)=33\\2x+9.50=33\\2x=33-9.50\\2x=23.50\\x=\$11.75[/tex]
therefore
The cost of the doll is $11.75
Answer:
Doll cost = $11.75.
Step-by-step explanation:
Given :A doll and a toy t-rex cost $33 together. If the t-rex toy costs $9.50 more than the doll.
To find : how much did the doll cost.
Solution : We have given
A doll and a toy t-rex cost $33 together.
Let the Doll cost = x .
According to question .
t-rex toy costs $9.50 more than the doll.
T-rex cost = $9.50+ x .
Then, A doll and a toy t-rex cost $33 together.
Doll cost + T oy t-rex cost = $33
Plugging the values
x + $9.50+ x =$33 .
2x + $9.50 =$33 .
On subtracting both sides by $9.50
2x =33 - 9.50
2x = 23.5.
On dividing both sides b y 2
x = $11.75
Doll cost =$11.75
Toy Cost = 9.50 +11.75.
Toy Cost = $21.25
Therefore, Doll cost = $11.75.
