Ben bought 3 oranges for 89 cents each and 4 apples for x dollars each. he spent $7.15 for the apples and oranges.

Multiply 3x.89 to get how much he spent on the oranges which would be $2.67 then subtract 7.15 from 2.67 7.15-2.67= which is 4.48, meaning he bought 4 apples for $4.48 divide this by 4 to solve for how much 1 apple costs which is $1.12

Each apple cost $1.12

Step-by-step explanation:

The total amount spent is the sum of the amounts spent on oranges added to the amount spent on apples. Given that Ben bought 3 oranges for 89 cents each, amount spent on oranges

= 3 * $0.89

= $2.67

If Ben bought 4 apples for x dollars each, amount spent on apples

= 4x

Total amount spent is $7.15

2.67 + 4x = 7.15

4x = 7.15 - 2.67

4x = 4.48

x = $1.12

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
