D'John saves $8 per week. Arthur saves 4 times the amount D'John saves in the same week. Write an equation that shows how to find the amount "a" Arthur saves. Then solve the equation

The equation is a = 4d and the solution is a = 32. This means that Arthur saves $32 per week.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Saving per week= $8

Now,

To write an equation that shows how to find the amount “a” Arthur saves, we need to use the given information. We are told that Arthur saves 4 times the amount D’ John saves in the same week.

We can write this as:

a = 4d

where a is the amount Arthur saves and d is the amount D’John saves. We are also told that D’John saves $8 per week. We can substitute this value into the equation and solve for a. We get:

a = 4d a = 4(8) a = 32

Therefore, by the equation the answer will be a = 4d, a = 32 and  Arthur saves $32 per week.
