Answer 1

`\$1.50b+\$3g=\$12`

Explanation:

Given:

Bananas cost $1.50 per pound,

Guavas cost $3.00 per pound.

Kiran spends $12 on fruit for a breakfast.

Let b be the number of pounds of bananas Kiran buys.

Let g be the number of pounds of guavas Kiran buys.

Question asked: ( omitted to asked here )

a. Write an equation relating the two variables.

Solution:

Cost of banana per pound = $1.50

Cost of banana for
`b` pound = $1.50
`* b`

Similarly, Cost of guavas per pound = $3.00

Cost of guavas for
`g` pound = $3.00
`* g`

Now,

Total money spent on fruits by Kiran = $12

Cost of banana for
`b` pound + Cost of guavas for
`g` pound = $12

The equation will be:-

$1.50
`* b` + $3.00
`* g` = $12

`\$1.50b+\$3g=\$12`
