John had to pay a combined electric and gas bill $150. The electric portion of the bill was $90. What is the ratio of money spen
tatuchka [14]

Given:

John had to pay a combined electric and gas bill $150.

The electric portion of the bill was $90.

To find:

The ratio of money spent on electric to that on gas.

Solution:

Let x be the amount of gas bill.

The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150.  So,

90+x=150

x=150-90

x=60

The gas portion of the bill was $60.

The ratio of money spent on electric to that on gas is:

\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}

\text{Required Ratio}=\dfrac{90}{60}

\text{Required Ratio}=\dfrac{3}{2}

\text{Required Ratio}=3:2

Therefore, the ratio of money spent on electric to that on gas is 3:2.

Vika [28.1K]
The value would be 4.

First, you have to do 4 + 3 because it's in parenteces. This equals 7
Secondly, you have to do 2 x 7, which is 14.
Last you have to do 18 - 14 which is 4.
