Lily went for 8 rides at the county fair. Some rides were on the merry go round and the rest were on the pirate ship. The total cost of all the rides was $6.30. Each pirate ship ride cost $0.60 and each merry go round cost $0.90. Construct an equation to find out how many pirate ship rides Lily took.



Answer :

The answer is .60s+.90m= 6.30

The equation form would be;  x0.60s + y0.90 = 6.30

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.

So, unit price of something is price of 1 thing.

Thus Let we're taking about price of mangoes, then unit price will denote the price of 1 mango.

We have been given Lily went for 8 rides at the county fair.

The total cost of all the rides was $6.30.

Each pirate ship ride cost $0.60

each merry go round cost $0.90.

The equation form would be;

x0.60s + y0.90 = 6.30

If x = 8 then,

x0.60s + y0.90 = 6.30

(8)0.60s + y0.90 = 6.30

 y0.90 = 6.30 - 4.80

y0.90 = 1.50

y = 1.66

Hence, the pirate ship rides Lily took would be 2 approximatly.
