Anyone know how to do this or has the answer?? Much appreciated ☺️

$200

Step-by-step explanation:

For this one, you want to make algebraic equations. In this case, they would be r+7v=120 and r+10v=150 (where r is the register fee and v is the cost of a visit).

To solve simultaneous equations with a like term (when they have the same sign in front), you can solve by subtracting one equation from the other. This gives (r-r)+(10v-7v)=(150-120) or 3v=30, which can be solved to v=10.

To work out r, we can sub the known value of v (10) for v in either equation. This gives r+(10×10)=150 or r+100=150. This can be solved to r=50.

This makes the expression c=50+10n (where c is the total cost and n is the number of visits.

Lisa went 15 times, so this becomes c=50+(10×15) or c=50+150, which gives c=200.
