The Mathscribe Fruit Stand sells apples for \$2 each. Let’s use the variable $a$ for the number of apples you want to buy. For each of the values of $a$ shown in the table below, how much would it cost to buy $a$ apples at the fruit stand?

$a$ = number of apples | cost of $a$ apples |
---|

If each apple costs \$2, then the cost of $a$ apples = $2a$.

The Mathscribe Fruit Stand also sells bananas. They cost \$3 each. For each of the values of $b$ shown in the table below, how much would it cost to buy $b$ bananas?

$b$ = number of bananas | cost of $b$ bananas |
---|

What is an expression for the cost of $b$ bananas? |

Let’s say you want to buy $a$ apples and $b$ bananas at the same time. Since apples cost \$2 each and bananas cost \$3 each, the total amount of money you’ll spend is $2a+3b$. This is pictured on the grid to the left; the $a$ rectangles in the farther-left stack (with a width of 2) represent the cost of $a$ apples, while the $b$ rectangles in the farther-right stack (with a width of 3) represent the cost of $b$ bananas.

For each row of the table below, fill in the value of this expression for the given number of apples and bananas.

$a$ = number of apples $b$ = number of bananas | $2a+3b$ = cost of apples and bananas |

The Mathscribe Fruit Stand has moved to the tropics. They are now selling coconuts for \$4 each, and dates for \$5 each. This is pictured on the grid to the left, as in multiqn. If you want to buy $c$ coconuts and $d$ dates, what is an expression for the total amount of money you will spend? |

For each row of the table below, fill in the amount of money you need to spend if you want to buy $c$ coconuts and $d$ dates.

$c$ = number of coconuts $d$ = number of dates | $4c+5d$ = total cost |
---|

You want to buy $a$ apples, $b$ bananas, and $d$ dates from the fruit stand. As before, apples cost \$2, bananas cost \$3, and dates cost \$5. You would also like to buy a basket to hold your fruit, which costs \$8. An expression for the total amount of money you need to spend to do all this is $2a+3b+5d+8$.

This is pictured on the grid to the left, with the leftmost stack of rectangles representing the cost of $a$ apples, the next stack representing the cost of $b$ bananas, the next stack representing the cost of $d$ dates, and the rectangle on the right representing the price of the basket.

For each row of this table, what is the total amount you will be spending?

$a=$ number of apples $b=$ number of bananas $d=$ number of dates | $2a+3b+5d+8$ = total cost |
