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.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
