At a supermarket, oranges cost [tex] \$1.30 [/tex] per pound and pears cost [tex] \$1.90 [/tex] per pound. Misha spent less than [tex] \$10.00 [/tex] on 2 pounds of oranges and [tex] x [/tex] pounds of pears. Which inequality represents this situation?

A. [tex] 2(1.30) + 1.90x \ \textless \ 10.00 [/tex]
B. [tex] 2(1.90) + 1.30x \ \textless \ 10.00 [/tex]
C. [tex] (1.30 + 1.90)x \ \textless \ 10.00 [/tex]
D. [tex] 2(1.30 + 1.90)x \ \textless \ 10.00 [/tex]


Sagot :

To determine which inequality represents Misha's spending at the supermarket, let's break down the situation step by step.

1. Given Cost Per Pound:
- The cost of oranges is [tex]$1.30 per pound. - The cost of pears is $[/tex]1.90 per pound.

2. Misha's Shopping:
- Misha bought 2 pounds of oranges.
- Misha also bought [tex]\( x \)[/tex] pounds of pears.
- The total amount Misha spent is less than $10.00.

3. Calculating the Cost of Oranges:
- Misha bought 2 pounds of oranges, so the total cost of the oranges is:
[tex]\[ 2 \text{ pounds} \times 1.30 \text{ dollars/pound} = 2.60 \text{ dollars} \][/tex]

4. Setting Up the Inequality:
- Let [tex]\( x \)[/tex] be the number of pounds of pears.
- The cost of [tex]\( x \)[/tex] pounds of pears would be:
[tex]\[ 1.90 \text{ dollars/pound} \times x = 1.90x \text{ dollars} \][/tex]
- The total expenditure combining the cost of oranges and pears is:
[tex]\[ 2.60 \text{ dollars} + 1.90x \text{ dollars} < 10.00 \text{ dollars} \][/tex]

5. Identifying the Correct Inequality:
- We must choose from the following options:
[tex]\[ \left(\frac{1.30 + 1.90}{2}\right)x < 10.00 \][/tex]
[tex]\[ 2(1.30)+1.90x < 10.00 \][/tex]
[tex]\[ 2(1.90)+1.30x < 10.00 \][/tex]
[tex]\[ 2(1.30 + 1.90)x < 10.00 \][/tex]

Our derived inequality for Misha's total spending was:
[tex]\[ 2.60 + 1.90x < 10.00 \][/tex]

Comparing this to the given options, we find that the correct inequality is:
[tex]\[ 2(1.30) + 1.90x < 10.00 \][/tex]

Therefore, the inequality that represents this situation is:
[tex]\[ 2(1.30)+1.90 x<10.00 \][/tex]
